single-chip risc microcontroller that integrates a risc cpu core using an original renesas architecture with peripheral functions required for system configuration. the cpu has a risc-type instruction set. most instructions can be executed in one state (one system clock cycle), which greatly improves instruction execution speed. in addition, the 32-bit internal architecture enhances data processing power. with this cpu, it has become possible to assemble low-cost, high-performance/high-functionality systems even for applications such as real-time control, which could not previously be handled by microcontrollers because of their high-speed processing requirements. in addition, the sh7050 series includes on-chip peripheral functions necessary for synchronous configuration, such as large-capacity rom and ram, a direct memory access controller (dmac), timers, a serial communication interface (sci), a/d converter, interrupt controller (intc), and i/o ports. rom and sram can be directly connected by means of an external memory access support function, greatly reducing system cost. there are versions of on-chip rom: mask rom and flash memory. the flash memory can be programmed with a programmer that supports sh7050 series programming, and can also be programmed and erased by software. this hardware manual describes the sh7050 series hardware. refer to the programming manual for a detailed description of the instruction set. related manual sh7050 series instructions sh-1/sh-2/sh-dsp software manual (document no. rej09b0171-0500o) please consult your

817 section 1 overview rev. 5.00 jan 06, 2006 page 1 of 818 rej09b0273-0500 section 1 overview 1.1 features the sh7050 series is a single-chip risc microcontroller that integrates a risc cpu core using an original renesas architecture with peripheral functions required for system configuration. the cpu has a risc-type instruction set. most instructions can be executed in one state (one system clock cycle), which greatly improves instruction execution speed. in addition, the 32-bit internal architecture enhances data processing power. with this cpu, it has become possible to assemble low-cost, high-performance/high-functionality systems even for applications such as real-time control, which could not previously be handled by microcontrollers because of their high-speed processing requirements. in addition, the sh7050 series includes on-chip peripheral functions necessary for synchronous configuration, such as large-capacity rom and ram, a direct memory access controller (dmac), timers, a serial communication interface (sci), a/d converter, interrupt controller (intc), and i/o ports. rom and sram can be directly connected by means of an external memory access support function, greatly reducing system cost. there are versions of on-chip rom: mask rom and f-ztat tm (flexible zero turn around time) with flash memory. the flash memory can be programmed with a programmer that supports sh7050 series programming, and can also be programmed and erased by software. this enables the chip to be programmed on the user side while mounted on a board. the features of the sh7050 series are summarized in table 1.1. note : f-ztat is a trademark of renesas technology corp. section 1 overview rev. 5.00 jan 06, 2006 page 2 of 818 rej09b0273-0500 table 1.1 sh7050 series

note: * mask rom version section 2 cpu rev. 5.00 jan 06, 2006 page 21 of 818 rej09b0273-0500 section 2 cpu 2.1 register configuration the register set consists of sixteen 32-bit general registers, three 32-bit control registers and four 32-bit system registers. 2.1.1 general registers (rn) the sixteen 32-bit general registers (rn) are numbered r0?r15. general registers are used for data processing and address calculation. r0 is also used as an index register. several instructions have r0 fixed as their only usable register. r15 is used as the hardware stack pointer (sp). saving and recovering the status register (sr) and program counter (pc) in exception processing is accomplished by referencing the stack using r15. figure 2.1 shows the general registers. r0 * 1 r1 r2 r3 r4 r5 r6 r7 r8 r9 r10 r11 r12 r13 r14 r15, sp (hardware stack pointer) * 2 0 31 1. 2. r0 functions as an index register in the indirect indexed register addressing mode and indirect indexed gbr addressing mode. in some instructions, r0 functions as a fixed source register or destination register. r15 functions as a hardware stack pointer (sp) during exception processing. notes: figure 2.1 general registers section 2 cpu rev. 5.00 jan 06, 2006 page 22 of 818 rej09b0273-0500 2.1.2 control registers the 32-bit control registers consist of the 32-bit status register (sr), global base register (gbr), and vector base register (vbr). the status register indicates processing states. the global base register functions as a base address for the indirect gbr addressing mode to transfer data to the registers of on-chip peripheral modules. the vector base register functions as the base address of the exception processing vector area (including interrupts). figure 2.2 shows a control register.

only. bits i0?i3: interrupt mask bits. m and q bits: used by the div0u, div0s, and div1 instructions. global base register (gbr): indicates the base address of the indirect gbr addressing mode. the indirect gbr addressing mode is used in data transfer for on-chip peripheral modules register areas and in logic operations. vector base register (vbr): stores the base address of the exception processing vector area. sr: status register t bit: the movt, cmp/cond, tas, tst, bt (bt/s), bf (bf/s), sett, and clrt instructions use the t bit to indicate true (1) or false (0). the addv, addc, subv, subc, div0u, div0s, div1, negc, shar, shal, shlr, shll, rotr, rotl, rotcr, and rotcl instructions also use the t bit to indicate carry/borrow or overflow/underflow. figure 2.2 control register configuration section 2 cpu rev. 5.00 jan 06, 2006 page 23 of 818 rej09b0273-0500 2.1.3 system registers system registers consist of four 32-bit registers: high and low multiply and accumulate registers (mach and macl), the procedure register (pr), and the program counter (pc). the multiply and accumulate registers store the results of multiply and accumulate operations. the procedure

operands are always longwords (32 bits). when the memory operand is only a byte (8 bits) or a word (16 bits), it is sign-extended into a longword when loaded into a register (figure 2.4). 31 0 longword figure 2.4 data format in registers 2.2.2 data format in memory memory data formats are classified into bytes, words, and longwords. byte data can be accessed from any address, but an address error will occur if you try to access word data starting from an address other than 2n or longword data starting from an address other than 4n. in such cases, the data accessed cannot be guaranteed. the hardware stack area, referred to by the hardware stack pointer (sp, r15), uses only longword data starting from address 4n because this area holds the program counter and status register (figure 2.5). 31 0 15 23 7 byte byte byte byte word word address 2n address 4n longword address m address m + 2 address m + 1 address m + 3 figure 2.5 data format in memory section 2 cpu rev. 5.00 jan 06, 2006 page 25 of 818 rej09b0273-0500 2.2.3 immediate data format byte (8 bit) immediate data resides in an instruction code. immediate data accessed by the mov, add, and cmp/eq instructions is sign-extended and handled in registers as longword data. immediate data accessed by the tst, and, or, and xor instructions is zero-extended and handled as longword data. consequently, and instructions with immediate data always clear the upper 24 bits of the destination register. word or longword immediate data is not located in the instruction code, but instead is stored in a memory table. an immediate data transfer instruction (mov) accesses the memory table using the pc relative addressing mode with displacement. 2.3 instruction features 2.3.1 risc-type instruction set all instructions are risc type. this section details their functions. 16-bit fixed length : all instructions are 16 bits long, increasing program code efficiency. one instruction per cycle : the microprocessor can execute basic instructions in one cycle using the pipeline system. instructions are executed in 50 ns at 20 mhz. data length : longword is the standard data length for all operations. memory can be accessed in bytes, words, or longwords. byte or word data accessed from memory is sign-extended and handled as longword data. immediate data is sign-extended for arithmetic operations or zero- extended for logic operations. it also is handled as longword data (table 2.2). table 2.2 sign extension of word data sh7050 series cpu description example of conventional cpu mov.w @(disp,pc),r1 add r1,r0 ......... .data.w h'1234 data is sign-extended to 32 bits, and r1 becomes h'00001234. it is next operated upon by an add instruction. add.w #h'1234,r0 note: @(disp, pc) accesses the immediate data. load-store architecture : basic operations are executed between registers. for operations that involve memory access, data is loaded to the registers and executed (load-store architecture). instructions such as and that manipulate bits, however, are executed directly in memory. section 2 cpu rev. 5.00 jan 06, 2006 page 26 of 818 rej09b0273-0500 delayed branch instructions : unconditional branch instructions are delayed. executing the instruction that follows the branch instruction and then branching reduces pipeline disruption during branching (table 2.3). there are two types of conditional branch instructions: delayed branch instructions and ordinary branch instructions. table 2.3 delayed branch instructions sh7050 series cpu description example of conventional cpu bra trget add r1,r0 executes an add before branching to trget add.w r1,r0 bra trget multiplication/accumulation operation : 16-bit 16-bit 32-bit multiplication operations are executed in one to two cycles. 16-bit 16-bit + 64-bit 64-bit multiplication/accumulation operations are executed in two to three cycles. 32-bit 32-bit 64-bit and 32-bit 32-bit + 64bit 64-bit multiplication/accumulation operations are executed in two to four cycles. t bit : the t bit in the status register changes according to the result of the comparison, and in turn is the condition (true/false) that determines if the program will branch. the number of instructions that change the t bit is kept to a minimum to improve the processing speed (table 2.4). table 2.4 t bit sh7050 series cpu description example of conventional

s processing state flow. for a reset, the initial values of the program counter (pc) (execution start address) and stack pointer (sp) are fetched from the exception processing vector table and stored; the cpu then branches to the execution start address and execution of the program begins. for an interrupt, the stack pointer (sp) is accessed and the program counter (pc) and status register (sr) are saved to the stack area. the exception service routine start address is fetched from the exception processing vector table; the cpu then branches to that address and the program starts executing, thereby entering the program execution state. program execution state : in the program execution state, the cpu sequentially executes the program. power-down state : in the power-down state, the cpu operation halts and power consumption declines. the sleep instruction places the cpu in the sleep mode or the software standby mode. this state has two modes: sleep mode and standby mode. bus release state : in the bus release state, the cpu releases access rights to the bus to the device that has requested them. section 3 operating modes rev. 5.00 jan 06, 2006 page 51 of 818 rej09b0273-0500 section 3 operating modes 3.1 operating mode selection the sh7050 series has five operating modes that are selected by pins md3 to md0 and fwe. the mode setting pins should not be changed during operation of the sh7050 series, and only the setting combinations shown in table 3.1 should be used. table 3.1 operating mode selection pin settings operating mode no. fwe md3 md2 md1 md0 mode name on-chip rom area 0 bus width mode 0 0 * * 0 0 mcu expanded mode disabled 8 bits mode 1 0 0 1 16 bits mode 2 0 1 0 enabled set by bcr1 mode 3 0 1 1 mcu single-chip mode enabled ?

(the reset exception processing table holds the initial values of pc and sp.) all exception sources are given different vector numbers and vector table address offsets, from which the vector table addresses are calculated. during exception processing, the start addresses of the exception service routines are fetched from the exception processing vector table, which indicated by this vector table address. table 5.3 shows the vector numbers and vector table address offsets. table 5.4 shows how vector table addresses are calculated. table 5.3 exception processing vector table exception

should be kept at low for at least the duration of the oscillation settling time when applying power or when in standby mode (when the clock circuit is halted) or at least 20 t cyc (when the clock circuit is running). during power-on reset, cpu internal status and all registers of on-chip peripheral modules are initialized. see appendix b, pin status, for the status of individual pins during the power-on reset status. in the power-on reset status, power-on reset exception processing starts when the res pin is first driven low for a set period of time and then returned to high. the cpu will then operate as follows: 1. the initial value (execution start address) of the program counter (pc) is fetched from the exception processing vector table. 2. the initial value of the stack pointer (sp) is fetched from the exception processing vector table. 3. the vector base register (vbr) is cleared to h'00000000 and the interrupt mask bits (i3?i0) of the status register (sr) are set to h'f (1111). 4. the values fetched from the exception processing vector table are set in the program counter (pc) and sp and the program begins executing. be certain to always perform power-on reset processing when turning the system power on. section 5 exception processing rev. 5.00 jan 06, 2006 page 66 of 818 rej09b0273-0500 5.3 address errors 5.3.1 address error sources address errors occur

which the address error occurred ends. when the executing instruction then finishes, address error exception processing starts up. the cpu operates as follows: 1. the status register (sr) is saved to the stack. 2. the program counter (pc) is saved to the stack. the pc value saved is the start address of the instruction to be executed after the last executed instruction. 3. the exception service routine start address is fetched from the exception processing vector table that corresponds to the address error that occurred and the program starts executing from that address. the jump that occurs is not a delayed branch. 5.4 interrupts 5.4.1 interrupt sources table 5.6 shows the sources that start up interrupt exception processing. these are divided into nmi, user breaks, irq and on-chip peripheral modules. table 5.6 interrupt sources type request source number of sources nmi nmi pin (external input) 1 user break user break controller 1 irq irq0 ? irq7 (external input) 8 on-chip

interrupt source is allocated a different vector number and vector table offset. see section 6, interrupt controller, and table 6.3, interrupt exception processing vectors and priorities, for more information on vector numbers and vector table address offsets. section 5 exception processing rev. 5.00 jan 06, 2006 page 68 of 818 rej09b0273-0500 5.4.2 interrupt priority level the interrupt priority order is predetermined. when multiple interrupts occur simultaneously (overlap), the interrupt controller (intc) determines their relative priorities and starts up processing according to the results. the priority order of interrupts is expressed as priority levels 0?16, with priority 0 the lowest and priority 16 the highest. the nmi interrupt has priority 16 and cannot be masked, so it is always accepted. the user break interrupt priority level is 15. irq interrupts and on-chip peripheral module interrupt priority levels can be set freely using the intc?s interrupt priority level setting registers a through h (ipra to iprh) as shown in table 5.7. the priority levels that can be set are 0?15. level 16 cannot be set. table 5.7 interrupt priority order type priority level comment nmi 16 fixed priority level. cannot be masked. user break 15 fixed priority level. irq 0?15 set with interrupt priority level setting registers a through h (ipra to iprh). on-chip peripheral module 0?15 set with interrupt priority level setting registers a through h (ipra to iprh). 5.4.3 interrupt exception processing when an interrupt occurs, its priority level is ascertained by the interrupt controller (intc). nmi is always accepted, but other interrupts are only accepted if they have a priority level higher than the priority level set in the interrupt mask bits (i3?i0) of the status register (sr). when an interrupt is accepted, exception processing begins. in interrupt exception processing, the cpu saves sr and the program counter (pc) to the stack. the priority level value of the accepted interrupt is written to sr bits i3?i0. for nmi, however, the priority level is 16, but the value set in i3?i0 is h'f (level 15). next, the start address of the exception service routine is fetched from the exception processing vector table for the accepted interrupt, that address is jumped to and execution begins. section 5 exception processing rev. 5.00 jan 06, 2006 page 69 of 818 rej09b0273-0500 5.5 exceptions triggered by instructions 5.5.1 types of exceptions triggered by instructions exception processing can be triggered by trap instructions, general illegal instructions, and illegal slot instructions, as shown in table 5.8. table 5.8 types of exceptions triggered by instructions type source instruction comment trap instructions trapa ? illegal slot instructions undefined code placed immediately after a delayed branch instruction (delay slot) and instructions that rewrite the pc delayed branch instructions: jmp, jsr, bra, bsr, rts, rte, bf/s, bt/s, bsrf, braf instructions that rewrite the pc: jmp, jsr, bra, bsr, rts, rte, bt, bf, trapa, bf/s, bt/s, bsrf, braf general illegal instructions undefined code anywhere besides in a delay slot ? 5.5.2 trap instructions when a trapa instruction is executed, trap instruction exception processing starts up. the cpu operates as follows: 1. the status register (sr) is saved to the stack. 2. the program counter (pc) is saved to the stack. the pc value saved is the start address of the instruction to be executed after the trapa instruction. 3. the exception service routine start address is fetched from the exception processing vector table that corresponds to the vector number specified in the trapa instruction. that address is jumped to and the program starts executing. the jump that occurs is not a delayed branch. section 5 exception processing rev. 5.00 jan 06, 2006 page 70 of 818 rej09b0273-0500 5.5.3 illegal slot instructions an instruction placed immediately after a delayed branch instruction is said to be placed in a delay slot. when the instruction placed in the delay slot is undefined code, illegal slot exception processing starts up when that undefined code is decoded. illegal slot exception processing also starts up when an instruction that rewrites the program counter (pc) is placed in a delay slot. the processing starts when the instruction is decoded. the cpu handles an illegal slot instruction as follows: 1. the status register (sr) is saved to the stack. 2. the program counter (pc) is saved to the stack. the pc value saved is the jump address of the delayed branch instruction immediately before the undefined code or the instruction that rewrites the pc. 3. the exception service routine start address is fetched from the exception processing vector table that corresponds to the exception that occurred. that address is jumped to and the program starts executing. the jump that occurs is not a delayed branch. 5.5.4 general illegal instructions when undefined code placed anywhere other than immediately after a delayed branch instruction (i.e., in a delay slot) is decoded, general illegal instruction exception processing starts up. the cpu handles general illegal instructions the same as illegal slot instructions. unlike processing of illegal slot instructions, however, the program counter value stored is the start address of the undefined code. section 5 exception processing rev. 5.00 jan 06, 2006 page 71 of 818 rej09b0273-0500 5.6 when exception sources are not accepted when an address error or interrupt is generated after a delayed branch instruction or interrupt- disabled instruction, it is sometimes not accepted immediately but stored instead, as shown in table 5.9. when this happens, it will be accepted when an instruction that can accept the exception is decoded. table 5.9 generation of exception sources immediately after a delayed branch instruction or interrupt-disabled instruction exception source point of occurrence address error interrupt immediately after a delayed branch instruction * 1 not accepted not accepted immediately after an interrupt-disabled instruction * 2 accepted not accepted notes: 1. delayed branch instructions: jmp, jsr, bra, bsr, rts, rte, bf/s, bt/s, bsrf, braf 2. interrupt-disabled instructions: ldc, ldc.l, stc, stc.l, lds, lds.l, sts, sts.l 5.6.1 immediately after a delayed branch instruction when an instruction placed immediately after a delayed branch instruction (delay slot) is decoded, neither address errors nor interrupts are accepted. the delayed branch instruction and the instruction located immediately after it (delay slot) are always executed consecutively, so no exception processing occurs during this period. 5.6.2 immediately after an interrupt-disabled instruction when an instruction immediately following an interrupt-disabled instruction is decoded, interrupts are not accepted. address errors are accepted. section 5 exception processing rev. 5.00

5.8 notes on use 5.8.1 value of stack pointer (sp) the value of the stack pointer must always be a multiple of four. if it is not, an address error will occur when the stack is accessed during exception processing. 5.8.2 value of vector base register (vbr) the value of the vector base register must always be a multiple of four. if it is not, an address error will occur when the stack is accessed during exception processing. 5.8.3 address errors caused by stacking of address error exception processing when the stack pointer is not a multiple of four, an address error will occur during stacking of the exception processing (interrupts, etc.) and address error exception processing will start up as soon as the first exception processing is ended. address errors will then also occur in the stacking for this address error exception processing. to ensure that address error exception processing does not go into an endless loop, no address errors are accepted at that point. this allows program control to be shifted to the address error exception service routine and enables error processing. when an address error occurs during exception processing stacking, the stacking bus cycle (write) is executed. during stacking of the status register (sr) and program counter (pc), the sp is ?4 for both, so the value of sp will not be a multiple of four after the stacking either. the address value output during stacking is the sp value, so the address where the error occurred is itself output. this means the write data stacked will be undefined. section 5 exception processing rev.

interrupt controller (intc) ascertains the priority of interrupt sources and controls interrupt requests to the cpu. the intc has registers for setting the priority of each interrupt which can be used by the user to order the priorities in which the interrupt requests are processed. 6.1.1 features the intc has the following features: ? 16 levels of interrupt priority: by setting the eight interrupt-priority level registers, the priorities of irq interrupts and on-chip peripheral module interrupts can be set in 16 levels for different request sources. ? nmi noise canceler function: nmi input level bits indicate the nmi pin status. by reading these bits with the interrupt exception service routine, the pin status can be confirmed, enabling it to be used as a noise canceler. ? notification of interrupt occurrence can be reported externally ( irqout pin). for example, it is possible to request bus rights if an external bus master is informed that a peripheral module interrupt has occurred when the lsi has released the bus rights. section 6 interrupt controller (intc) rev. 5.00 jan 06, 2006 page 76 of 818 rej09b0273-0500 6.1.2 block diagram figure 6.1 is a block

four types of interrupt sources: nmi, user breaks, irq, and on-chip peripheral modules. each interrupt has a priority expressed as a priority level (0 to 16, with 0 the lowest and 16 the highest). giving an interrupt a priority level of 0 masks it. 6.2.1 nmi interrupts the nmi interrupt has priority 16 and is always accepted. input at the nmi pin is detected by edge. use the nmi edge select bit (nmie) in the interrupt control register (icr) to select either the rising or falling edge. nmi interrupt exception processing sets the interrupt mask level bits (i3?i0) in the status register (sr) to level 15. 6.2.2 user break interrupt a user break interrupt has a priority of level 15, and occurs when the break condition set in the user break controller (ubc) is satisfied. user break interrupt requests are detected by edge and are held until accepted. user break interrupt exception processing sets the interrupt mask level bits (i3?i0) in the status register (sr) to level 15. for more information about the user break interrupt, see section 7, user break controller. 6.2.3 irq interrupts irq interrupts are requested by input from pins irq0 ? irq7 . set the irq sense select bits (irq0s?irq7s) of the interrupt control register (icr) to select low level detection or falling edge detection for each pin. the priority level can be set from 0 to 15 for each pin using the interrupt priority registers a and b (ipra?iprb). when irq interrupts are set to low level detection, an interrupt request signal is sent to the intc during the period the irq pin is low level. interrupt request signals are not sent to the intc when the irq pin becomes high level. interrupt request levels can be confirmed by reading the irq flags (irq0f?irq7f) of the irq status register (isr). when irq interrupts are set to falling edge detection, interrupt request signals are sent to the intc upon detecting a change on the irq pin from high to low level. irq interrupt request detection results are maintained until the interrupt request is accepted. confirmation that irq interrupt requests have been detected is possible by reading the irq flags (irq0f?irq7f) of the irq status register (isr), and by writing a 0 after reading a 1, irq interrupt request detection results can be withdrawn. section 6 interrupt controller (intc) rev. 5.00 jan 06, 2006 page 79 of 818 rej09b0273-0500 in irq interrupt exception processing, the interrupt mask bits (i3?i0) of the status register (sr) are set to the priority level value of the accepted irq interrupt. 6.2.4 on-chip peripheral module interrupts on-chip peripheral module interrupts are interrupts generated by the following on-chip peripheral modules: ? direct memory access controller (dmac) ? advanced timer unit (atu) ? compare match timer (cmt) ? a/d converter (a/d) ? serial communications interface (sci) ? watchdog timer (wdt) a different interrupt vector is assigned to each interrupt source, so the exception service routine does not have to decide which interrupt has occurred. priority levels between 0 and 15 can be assigned to individual on-chip peripheral modules in interrupt priority registers c?h (iprc? iprh). on-chip peripheral module interrupt exception processing sets the interrupt mask level bits (i3?i0) in the status register (sr) to the priority level value of the on-chip peripheral module interrupt that was accepted. 6.2.5 interrupt exception vectors and priority rankings table 6.3 lists interrupt sources and their vector numbers, vector table address offsets and interrupt priorities. each interrupt source is allocated a different vector number and vector table address offset. vector table addresses are calculated from vector numbers and address offsets. in interrupt exception processing, the exception service routine start address is fetched from the vector table indicated by the vector table address. see table 5.4, calculating exception processing vector table addresses. irq interrupts and on-chip peripheral module interrupt priorities can be set freely between 0 and 15 for each pin or module by setting interrupt priority registers a?h (ipra?iprh). the ranking of interrupt sources for iprc?iprh, however, must be the order listed under priority within ipr setting range in table 6.3 and cannot be changed. a power-on reset assigns priority level 0 to irq interrupts and on-chip peripheral module interrupts. if the same priority level is assigned to two or section 6 interrupt controller (intc) rev. 5.00 jan 06, 2006 page 80 of 818 rej09b0273-0500 more

setting a value from h'0 (0000) to h'f (1111) in each of the four-bit groups 15?12, 11?8, 7?4 and 3?0. interrupt priority rank becomes level 0 (lowest) by setting h'0, and level 15 (highest) by setting h'f. if multiple on-chip peripheral modules are assigned to same bit (dmac0 and dmac1, dmac2 and dmac3, atu6 to atu9, cmt0 and a/d0, and cmt1 and a/d1), those multiple modules are set to the same priority rank. ipra?iprh are initialized to h'0000 by a power-on reset. they are not initialized in standby mode. section 6 interrupt controller (intc) rev. 5.00 jan 06, 2006 page 86 of 818

control section 6 interrupt controller (intc) rev. 5.00 jan 06, 2006 page 89 of 818 rej09b0273-0500 6.4 interrupt operation 6.4.1 interrupt sequence the sequence of interrupt operations is explained below. figure 6.3 is a flowchart of the operations. 1. the interrupt request sources send interrupt request signals to the interrupt controller. 2. the interrupt controller selects the highest priority interrupt in the interrupt requests sent, following the priority levels set in interrupt priority level setting registers a?h (ipra?iprh). lower-priority interrupts are ignored. they are held pending until interrupt requests designated as edge-detect type are accepted. for irq interrupts, however, withdrawal is possible by accessing the irq status register (isr). see section 6.2.3, irq interrupts, for details. interrupts held pending due to edge detection are cleared by a power-on reset or a manual reset. if two of these interrupts have the same priority level or if multiple interrupts occur within a single module, the interrupt with the highest default priority or the highest priority within its ipr setting range (as indicated in table 6.3) is selected. 3. the interrupt controller compares the priority level of the selected interrupt request with the interrupt mask bits (i3?i0) in the cpu?s status register (sr). if the request priority level is equal to or less than the level set in i3?i0, the request is ignored. if the request priority level is higher than the level in bits i3?i0, the interrupt controller accepts the interrupt and sends an interrupt request signal to the cpu. 4. when the interrupt controller accepts an interrupt, a low level is output from the irqout pin. 5. the cpu detects the interrupt request sent from the interrupt controller when it decodes the next instruction to be executed. instead of executing the decoded instruction, the cpu starts interrupt exception processing (figure 6.5). 6. sr and pc are saved onto the stack. 7. the priority level of the accepted interrupt is copied to the interrupt mask level bits (i3 to i0) in the status register (sr). 8. when the accepted interrupt is sensed by level or is from an on-chip peripheral module, a high level is output from the irqout pin. when the accepted interrupt is sensed by edge, a high level is output from the irqout pin at the point when the cpu starts interrupt exception processing instead of instruction execution as noted in (5) above. however, if the interrupt controller accepts an interrupt with a higher priority than one it is in the midst of accepting, the irqout pin will remain low level. 9. the cpu reads the start address of the exception service routine from the exception vector table for the accepted interrupt, jumps to that address, and starts executing the program there. this jump is not a delay branch. section 6 interrupt controller (intc) rev. 5.00 jan 06, 2006 page 90 of 818 rej09b0273-0500 no yes nmi? no yes user break? no yes level 15

exception vector table notes: 1. 2. irqout is the same signal as the interrupt request signal to the cpu (see figure 6.1). thus, it is output when there is a higher priority interrupt request than the one in the i3 to i0 bits of the sr. when the accepted interrupt is sensed by edge, the irqout pin becomes high level at the point when the cpu starts interrupt exception processing instead of instruction execution (before sr is saved to the stack). if the interrupt controller has accepted another interrupt with a higher priority and has output an interrupt request to the cpu, the irqout pin will remain low level. figure 6.3 interrupt sequence flowchart section 6 interrupt controller (intc) rev. 5.00 jan 06, 2006 page 91 of 818 rej09b0273-0500 6.4.2 stack after interrupt exception

rej09b0273-0500 section 7 user break controller (ubc) 7.1 overview the user break controller (ubc) provides functions that simplify program debugging. break conditions are set in the ubc and a user break interrupt is generated according to the conditions of the bus cycle generated by the cpu, dmac, or dtc. this function makes it easy to design an effective self-monitoring debugger, enabling the chip to easily debug programs without using a large in-circuit emulator. 7.1.1 features the features of the user break controller are: ? break compare conditions can be set: ? address ? cpu cycle/dma cycle ? instruction fetch or data access ? read or write ? operand size: byte/word/longword ? user break interrupt generated upon satisfying break conditions. a user-designed user break interrupt exception processing routine can be run. ? select either to break in the cpu instruction fetch cycle before the instruction is executed or after. section 7 user break controller (ubc) rev. 5.00 jan

user break controller (ubc) rev. 5.00 jan 06, 2006 page 102 of 818 rej09b0273-0500 7.3 operation 7.3.1 flow of the user break operation the flow from setting of break conditions to user break interrupt exception processing is described below: 1. the user break addresses are set in the user break address register (ubar), the desired masked bits in the addresses are set in the user break address mask register (ubamr) and the breaking bus cycle type is set in the user break bus cycle register (ubbr). if even one of the three groups of the ubbr?s cpu cycle/peripheral cycle select bits (cp1, cp0), instruction fetch/data access select bits (id1, id0), and read/write select bits (rw1, rw0) is set to 00 (no user break interrupt is generated), no user break interrupt will be generated even if all other conditions are in agreement. when using user break interrupts, always be certain to establish bit conditions for all of these three groups. 2. the ubc uses the method shown in figure 7.2 to judge whether set conditions have been fulfilled. when the set conditions are satisfied, the ubc sends a user break interrupt request signal to the interrupt controller (intc). 3. the interrupt controller checks the accepted user break interrupt request signal?s priority level. the user break interrupt has priority level 15, so it is accepted only if the interrupt mask level in bits i3?i0 in the status register (sr) is 14 or lower. when the i3?i0 bit level is 15, the user break interrupt cannot be accepted but it is held pending until user break interrupt exception processing can be carried out. consequently, user break interrupts within nmi exception service routines cannot be accepted, since the i3?i0 bit level is 15. however, if the i3?i0 bit level is changed to 14 or lower at the start of the nmi exception service routine, user break interrupts become acceptable thereafter. section 6, interrupt controller, describes the handling of priority levels in greater detail. 4. the intc sends the user break interrupt request signal to the cpu, which begins user break interrupt exception processing upon receipt. see section 6.4, interrupt operation, for details on interrupt exception processing. section 7 user break controller (ubc) rev. 5.00 jan 06, 2006 page 103 of 818 rej09b0273-0500 sz1 sz0 user break interrupt rw1 rw0 id1 id0 cp1 cp0 ubarh/ubarl ubamrh/ubamrl 32 32

user break controller (ubc) rev. 5.00 jan 06, 2006 page 104 of 818 rej09b0273-0500 7.3.2 break on on-chip memory instruction fetch cycle on-chip memory (on-chip rom and/or ram) is always accessed as 32 bits in 1 bus cycle. therefore, 2 instructions can be retrieved in 1 bus cycle when fetching instructions from on-chip memory. at such times, only 1 bus cycle is generated, but by setting the start addresses of both instructions in the user break address register (ubar) it is possible to cause independent breaks. in other words, when wanting to effect a break using the latter of two addresses retrieved in 1 bus cycle, set the start address of that instruction in ubar. the break will occur after execution of the former instruction. 7.3.3 program counter (pc) values saved break on instruction fetch (before execution): the program counter (pc) value saved to the stack in user break interrupt exception processing is the address that matches the break condition. the user break interrupt is generated before the fetched instruction is executed. if a break condition is set in an instruction fetch cycle placed immediately after a delayed branch instruction (delay slot), or on an instruction that follows an interrupt-disabled instruction, however, the user break interrupt is not accepted immediately, but the break condition establishing instruction is executed. the user break interrupt is accepted after execution of the instruction that has accepted the interrupt. in this case, the pc value saved is the start address of the instruction that will be executed after the instruction that has accepted the interrupt. break on data access (cpu/peripheral): the program counter (pc) value is the top address of the next instruction after the last instruction executed before the user break exception processing started. when data access (cpu/peripheral) is set as a break condition, the place where the break will occur cannot be specified exactly. the break will occur at the instruction fetched close to where the data access that is to receive the break occurs. section 7 user break controller (ubc) rev. 5.00 jan 06, 2006 page 105 of 818 rej09b0273-0500 7.4 use

use 7.5.1 on-chip memory instruction fetch two instructions are simultaneously fetched from on-chip memory. if a break condition is set on the second of these two instructions but the contents of the ubc break condition registers are changed so as to alter the break condition immediately after the first of the two instructions is fetched, a user break interrupt will still occur when the second instruction is fetched. 7.5.2 instruction fetch at branches when a conditional branch instruction or trapa instruction causes a branch, instructions are fetched and executed as follows: 1. conditional branch instruction, branch taken: bt, bf trapa instruction, branch taken: trapa instruction fetch cycles: conditional branch fetch next-instruction overrun fetch next-instruction overrun fetch branch destination fetch instruction execution: conditional branch instruction execution branch destination instruction execution 2. when branching with a delayed conditional instruction: bt/s and bf/s instructions instruction fetch order: corresponding instruction fetch next instruction fetch (delay slot) overrun fetch of instruction after next branch destination instruction fetch instruction execution order: corresponding instruction execution delay slot instruction execution branch destination instruction execution when a conditional branch instruction or trapa instruction causes a branch, the branch destination will be fetched after the next instruction or the one after that does an overrun fetch. however, because the instruction that is the object of the break first breaks after a definite instruction fetch and execution, the kind of overrun fetch instructions noted above do not become objects of a break. if data access breaks are also included with instruction fetch breaks as break conditions, a break occurs because the instruction overrun fetch is also regarded as becoming a data break. section 7 user break controller (ubc) rev. 5.00 jan 06, 2006 page 108 of 818

break is in contention and is accepted in the decode stage for that instruction (or the next instruction), user break exception handling may not be performed after completion of the higher-priority exception handling routine (on return by rte). 7.5.4 break at non-delay branch instruction jump destination when a branch instruction with no delay slot (including exception handling) jumps to the jump destination instruction on execution of the branch, a user break will not be generated even if a user break condition has been set for the first jump destination instruction fetch. section 8 bus

from a slow device is completed, data buffers may not go off in time to prevent data conflicts with the next access. if there is a data conflict during memory access, the problem can be solved by inserting a wait in the access cycle. to enable detection of bus cycle starts, waits can be inserted between access cycles during continuous accesses of the same cs space by negating the csn signal once. 8.4.1 prevention of data bus conflicts for the two cases of write cycles after read cycles, and read cycles for a different area after read cycles, waits are inserted so that the number of idle cycles specified by the iw31 to iw00 bits of the bcr2 and the diw of the dcr occur. when idle cycles already exist between access cycles, only the number of empty cycles remaining beyond the specified number of idle cycles are inserted. figure 8.7 shows an example of idles between cycles. in this example, 1 idle between csn space cycles has been specified, so when a csm space write immediately follows a csn space read cycle, 1 idle cycle is inserted. section 8 bus state controller (bsc) rev. 5.00 jan 06, 2006 page 129 of 818 rej09b0273-0500 ck csn csm rd data csn space read csm space write

accesses. 0 to 3 cycles can be specified for cs space, and 0 to 1 cycle for dram space. section 8 bus state controller (bsc) rev. 5.00 jan 06, 2006 page 130 of 818 rej09b0273-0500 8.4.2 simplification

arbitration the sh7050 series has a bus arbitration function that, when a bus release request is received from an external device, releases the bus to that device. it also has two internal bus masters, the cpu and the dmac, dtc. the priority ranking for determining bus right transfer between these bus masters is: bus right request from external device > dmac > cpu therefore, an external device that generates a bus request is given priority even if the request is made during a dmac burst transfer. a bus request by an external device should be input at the breq pin. the signal indicating that the bus has been released is output from the back pin. figure 8.9 shows the bus right release procedure. breq = low sh7050 series breq accepted strobe pin: high-level output address,

jan 06, 2006 page 135 of 818 rej09b0273-0500 section 9 direct memory access controller (dmac) 9.1 overview the sh7050 series includes an on-chip four-channel direct memory access controller (dmac). the dmac can be used in place of the cpu to perform high-speed data transfers among external devices equipped with dack (transfer request acknowledge signal), external memories, memory- mapped external devices, and on-chip peripheral modules (except for the dmac, dtc, bsc, and ubc). using the dmac reduces the burden on the cpu and increases operating efficiency of the lsi as a whole. 9.1.1 features the dmac has the following features: ? four channels ? four gb of address space in the architecture ? byte, word, or longword selectable data transfer unit ? 16 mb (6,777,216 maximum) transfers ? single or dual address mode. dual address mode can be direct or indirect address transfer. ? single address mode: either the transfer source or transfer destination (peripheral device) is accessed by a dack signal while the other is accessed by address. one transfer unit of data is transferred in each bus cycle. ? dual address mode: both the transfer source and transfer destination are accessed by address. dual address mode can be direct or indirect address transfer. ? direct access: values set in a dmac internal register indicate the accessed address for both the transfer source and transfer destination. two bus cycles are required for one data transfer. indirect access: the value stored at the location pointed to by the address set in the dmac internal transfer source register is used as the address. operation is otherwise the same as direct access. this function can only be set for channel 3. ? channel function: transfer modes that can be set are different for each channel. (dual address mode indirect access can only be set for channel 1. only direct access is possible for the other channels). ? channel 0: single or dual address mode. external requests are accepted. ? channel 1: single or dual address mode. external requests are accepted. ? channel 2: dual address mode only. source address reload function operates every fourth transfer. section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 136 of 818 rej09b0273-0500 ? channel 3: dual address mode only. direct address transfer mode and indirect address transfer mode selectable. ? reload function: enables automatic reloading of the value set in the first source address register every fourth dma transfer. this function can be executed on channel 2 only. ? transfer requests: there are three dmac transfer activation requests, as indicated below. ? external request: from two dreq pins. dreq can be detected either by falling edge or by low level. external requests can only be received on channels 0 or 1. ? requests from on-chip peripheral modules: transfer requests from on-chip modules such as sci or a/d. these can be received by all channels. ? auto-request: the transfer request is generated automatically within the dmac. ? selectable bus modes: cycle-steal mode or burst mode ? two types of dmac channel priority ranking: ? fixed priority mode: always fixed ? round robin mode: sets the lowest priority level for the channel that received the execution request last ? cpu can be interrupted when the specified number of data transfers are complete. section 9

registers. one other control register is shared by all channels. there are two channel 0 dedicated registers, isar and idar, which preserve different initial transfer source and destination addresses than those of the sar0 and dar0. there is also an iar used by the indirect address mode. section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 139 of 818 rej09b0273-0500 table

the following procedure: 1. the dmac checks to see if transfer is enabled (de = 1, dme = 1, te = 0, nmif = 0, ae = 0). 2. when a transfer request comes and transfer has been enabled, the dmac transfers 1 transfer unit of data (determined by ts0 and ts1 setting). for an auto-request, the transfer begins automatically when the de bit and dme bit are set to 1. the dmatcr value will be decremented by 1 upon each transfer. the actual transfer flows vary by address mode and bus mode. 3. when the specified number of transfers have been completed (when dmatcr reaches 0), the transfer ends normally. if the ie bit of the chcr is set to 1 at this time, a dei interrupt is sent to the cpu. 4. when an address error occurs in the dmac or an nmi interrupt is generated, the transfer is aborted. transfers are also aborted when the de bit of the chcr or the dme bit of the dmaor are changed to 0. section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 151 of 818

transfer requests are usually generated in either the data transfer source or destination, but they can also be generated by devices and on-chip peripheral modules that are neither the source nor the destination. transfers can be requested in three modes: auto-request, external request, and on-chip peripheral module request. the request mode is selected in the rs3 ? rs0 bits of the dma channel control registers 0 ? 3 (chcr0 ? chcr3). auto-request mode: when there is no transfer request signal from an external source, as in a memory-to-memory transfer or a transfer between memory and an on-chip peripheral module unable to request a transfer, the auto-request mode allows the dmac to automatically generate a transfer request signal internally. when the de bits of chcr0 ? chcr3 and the dme bit of the dmaor are set to 1, the transfer begins (so long as the te bits of chcr0 ? chcr3 and the nmif and ae bits of dmaor are all 0). external request mode: in this mode a transfer is performed at the request signal ( dreq ) of an external device. choose one of the modes shown in table 9.3 according to the application system. when this mode is selected, if the dma transfer is enabled (de = 1, dme = 1, te = 0, nmif = 0, ae = 0), a transfer is performed upon a request at the dreq input. choose to detect dreq by either the falling edge or low level of the signal input with the ds bit of chcr0 ? chcr3 (ds = 0 is level detection, ds = 1 is edge detection). the source of the transfer request does not have to be the data transfer source or destination. table 9.3 selecting

request mode: in this mode a transfer is performed at the transfer request signal (interrupt request signal) of an on-chip peripheral module. as indicated in table 9.4, there are ten transfer request signals: five from the multifunction timer pulse unit (mtu), which are compare match or input capture interrupts; the receive data full interrupts (rxi) and transmit data empty interrupts (txi) of the two serial communication interfaces (sci); and the a/d conversion end interrupt (adi) of the a/d converter. when dma transfers are enabled (de = 1, dme = 1, te = 0, nmif = 0, ae = 0), a transfer is performed upon the input of a transfer request signal. the transfer request source need not be the data transfer source or transfer destination. however, when the transfer request is set by rxi (transfer request because sci ? s receive data is full), the transfer source must be the sci ? s receive data register (rdr). when the transfer request is set by txi (transfer request because sci ? s transmit data is empty), the transfer destination must be the sci ? s transmit data register (tdr). also, if the transfer request is set to the a/d converter, the data transfer destination must be the a/d converter register. section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 154 of 818 rej09b0273-0500 table 9.4 selecting on-chip peripheral module request modes with the rs

module, set the relevant interrupt enable bit for each module, and output an interrupt signal. when an on-chip peripheral module ? s interrupt request signal is used as a dma transfer request signal, interrupts for the cpu are not generated. when a dma transfer is conducted corresponding with one of the transfer request signals in table 9.4, it is automatically discontinued. in cycle steal mode this occurs in the first transfer, and in burst mode with the last transfer. 9.3.3 channel priority when the dmac receives simultaneous transfer requests on two or more channels, it selects a channel according to a predetermined priority order, either in a fixed mode or in round robin mode. these modes are selected by priority bits pr1 and pr0 in the dma operation register (dmaor). fixed mode: in these modes, the priority levels among the channels remain fixed. the following priority orders are available for fixed mode: ? ch0 > > > ? ch0 > > > ? ch2 > > > round robin mode: in round robin mode, each time the transfer of one transfer unit (byte, word or long word) ends on a given channel, that channel receives the lowest priority level (figure 9.3). the priority level in round robin mode immediately after a reset is ch0 > > > section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 156 of 818 rej09b0273-0500 ch1 > ch2 > ch3 > ch0 ch0 > ch1 > ch2 > ch3 ch2 > ch3 >

priority setting initial priority setting initial priority setting no change in priority. when channel 2 receives the lowest priority, the priorities of channel 0 and 1, which were above channel 2, are also shifted simultaneously. immedi- ately thereafter, if there is a transfer request for channel 1 only, channel 1 is given the lowest priority, and the priorities of channels 3 and 0 are simultaneously shifted down. when channel 1 is given the lowest priority, the priority of channel 0, which was above channel 1, is also shifted simultaneously. channel 1 is given the lowest priority. priority after transfer priority after transfer priority after transfer priority after transfer priority after transfer due to issue of a transfer request for channel 1 only. transfer on channel 1

example of changes in priority levels when transfer requests are issued simultaneously for channels 0 and 3, and channel 1 receives a transfer request during a transfer on channel 0. the dmac operates in the following manner under these circumstances: 1. transfer requests are issued simultaneously for channels 0 and 3. 2. since channel 0 has a higher priority level than channel 3, the channel 0 transfer is conducted first (channel 3 is on transfer standby). 3. a transfer request is issued for channel 1 during a transfer on channel 0 (channels 1 and 3 are on transfer standby). 4. at the end of the channel 0 transfer, channel 0 shifts to the lowest priority level. 5. at this point, channel 1 has a higher priority level than channel 3, so the channel 1 transfer comes first (channel 3 is on transfer standby). 6. when the channel 1 transfer ends, channel 1 shifts to the lowest priority level. 7. channel 3 transfer begins. 8. when the channel 3 transfer ends, channel 3 and channel 2 priority levels are lowered, giving channel 3 the lowest priority. transfer request channel waiting dmac operation channel priority issued for channels 0 and 3 issued for channel 1 0 > 1 > 2 > 3

page 158 of 818 rej09b0273-0500 9.3.4 dma transfer types the dmac supports the transfers shown in table 9.5. it can operate in the single address mode, in which either the transfer source or destination is accessed using an acknowledge signal, or dual address mode, in which both the transfer source and destination addresses are output. the dual address mode consists of a direct address mode, in which the output address value is the object of a direct data transfer, and an indirect address mode, in which the output address value is not the object of the data transfer, but the value stored at the output address becomes the transfer object address. the actual transfer operation timing varies with the bus mode. the dmac has two bus modes: cycle-steal mode and burst mode. table 9.5

transfer source and destination are external; one (selectable) is accessed by a dack signal while the other is accessed by an address. in this mode, the dmac performs the dma transfer in 1 bus cycle by simultaneously outputting a transfer request acknowledge dack signal to one external device to access it while outputting an address to the other end of the transfer. figure 9.5 shows a transfer between an external memory and an external device with dack in which the external device outputs data to the data bus while that data is written in external memory in the same bus cycle. dmac dack dreq external memory external device with dack superh microcomputer external address bus : data flow external data bus figure 9.5 data flow in single address mode two types of transfers are possible in the single address mode: (a) transfers between external devices with dack and memory-mapped external devices, and (b) transfers between external devices with dack and external memory. the only transfer requests for either of these is the external request ( dreq ). figure 9.6 shows the dma transfer timing for the single address mode. section 9 direct memory access controller (dmac) rev. 5.00

figure 9.6 example of dma transfer timing in the single address mode 9.3.6 dual address mode dual address mode is used for access of both the transfer source and destination by address. transfer source and destination can be accessed either internally or externally. dual address mode is subdivided into two other modes: direct address transfer mode and indirect address transfer mode. section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 161 of 818 rej09b0273-0500 direct address transfer mode: data is read from the transfer source during the data read cycle, and written to the transfer destination during the write cycle, so transfer is conducted in two bus cycles. at this time, the transfer data is temporarily stored in the dmac. with the kind of external memory transfer shown in figure 9.7, data is read from one of the memories by the dmac during a read cycle, then written to the other external memory during the subsequent write cycle. figure 9.8 shows the timing for this operation. data buffer address bus data bus address bus data bus memory transfer source module transfer destination module memory transfer source module transfer destination

dual address mode section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 163 of 818 rej09b0273-0500 indirect address transfer mode: in this mode the memory address storing the data you actually want to transfer is specified in dmac internal transfer source address register (sar3). therefore, in indirect address transfer mode, the dmac internal transfer source address register value is read first. this value is stored once in the dmac. next, the read value is output as the address, and the value stored at that address is again stored in the dmac. finally, the subsequent read value is written to the address specified by the transfer destination address register, ending one cycle of dmac transfer. in indirect address mode (figure 9.9), transfer destination, transfer source, and indirect address storage destination are all 16-bit external memory locations, and transfer in this example is conducted in 16-bit or 8-bit units. timing for this transfer example is shown in figure 9.10. in indirect address mode, one nop cycle (figure 9.10) is required until the data read as the indirect address is output to the address bus. when transfer data is 32-bit, the third and fourth bus cycles each need to be doubled, giving a required total of six bus cycles and one nop cycle for the whole operation. section 9 direct memory access controller (dmac) rev. 5.00 jan

are two bus modes: cycle steal and burst. cycle-steal mode: in the cycle steal mode, the bus right is given to another bus master after each one-transfer-unit (byte, word, or longword) dmac transfer. when the next transfer request occurs, the bus rights are obtained from the other bus master and a transfer is performed for one transfer unit. when that transfer ends, the bus right is passed to the other bus master. this is repeated until the transfer end conditions are satisfied. the cycle steal mode can be used with all categories of transfer destination, transfer source and transfer request.

dreq dreq pin sample timing number of states in bus cycle: the number of states in the bus cycle when the dmac is the bus master is controlled by the bus state controller (bsc) just as it is when the cpu is the bus master. the bus cycle in the dual address mode is controlled by wait state control register 1 (wcr1) while the single address mode bus cycle is controlled by wait state control register 2 (wcr2). for details, see section 8.3.2, wait state control. dreq dreq dreq dreq pin sampling timing and drak signal: in external request mode, the dreq pin is sampled by either falling edge or low-level detection. when a dreq input is detected, a dmac bus cycle is issued and dma transfer effected, at the earliest, after three states. however, in burst mode when single address operation is specified, a dummy cycle is inserted for the first bus cycle. in this case, the actual data transfer starts from the second bus cycle. data is transferred section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 170 of 818 rej09b0273-0500 continuously from the second bus cycle. the dummy cycle is not counted in the number of transfer cycles, so there is no need to recognize the dummy cycle when setting the tcr. dreq sampling from the second time begins from the start of the transfer one bus cycle prior to the dmac transfer generated by the previous sampling. drak is output once for the first dreq sampling, irrespective of transfer mode or dreq detection method. in burst mode, using edge detection, dreq is sampled for the first cycle only, so drak is also output for the first cycle only. therefore, the dreq signal negate timing can be ascertained, and this facilitates handshake operations of transfer requests with the dmac. cycle steal mode operations: in cycle steal mode, dreq sampling timing is the same irrespective of dual or single address mode, or whether edge or low-level dreq detection is used. for example, dmac transfer begins (figure 9.15), at the earliest, three cycles from the first sampling timing. the second sampling begins at the start of the transfer one bus cycle prior to the start of the dmac transfer initiated by the first sampling (i.e., from the start of the cpu(3) transfer). at this point, if dreq detection has not occurred, sampling is executed every cycle thereafter. as in figure 9.16, whatever cycle the cpu transfer cycle is, the next sampling begins from the start of the transfer one bus cycle before the dmac transfer begins. figure 9.15 shows an example of output during dack read and figure 9.16 an example of output

dmac transfer begins (figure 9.19), at the earliest, three cycles after the timing of the first sampling. the second sampling also begins from the start of the transfer one bus cycle before the start of the first dmac transfer. in burst mode, as long as transfer requests are issued, dmac transfer continues. therefore, the ? transfer one bus cycle before the start of the dmac transfer ? may be a dmac transfer. in burst mode, the dack output period is thesame as that of cycle steal mode. figure 9.20 shows the normal operation of this burst mode. section 9 direct memory access controller (dmac)

burst mode, single address, and level detection: dreq sampling timing in burst mode with single address and level detection is shown in figures 9.21 and 9.22. in burst mode with single address and level detection, a dummy cycle is inserted as one bus cycle, at the earliest, three cycles after timing of the first sampling. data during this period is undefined, and the dack signal is not output. nor is the number of dmac transfers counted. the actual dmac transfer begins after one dummy bus cycle output. the dummy cycle is not counted either at the start of the second sampling (transfer one bus cycle before the start of the first dmac transfer). therefore, the second sampling is not conducted from the bus cycle starting the dummy cycle, but from the start of the cpu(3) bus cycle. thereafter, as long the dreq is continuously sampled, no dummy cycle is inserted. dreq sampling timing during this period begins from the start of the transfer one bus cycle before the start of dmac transfer, in the same way as with cycle steal mode. as with the four samplings in figure 9.21, once dmac transfer is interrupted, a dummy cycle is again inserted at the start as soon as dmac transfer is resumed. the dack output period in burst mode is the same as in cycle steal mode. section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 180 of 818 rej09b0273-0500 ck dreq

of the first sampling. thereafter, dmac transfer continues until the end of the data transfer count set in the tcr. dreq sampling is not conducted during this period. therefore, drak is output on the

transfers, is decremented by 1 at the end of every single-transfer-unit transfer, regardless of whether the reload function is on or off. therefore, when using the reload function in the on state, a multiple of 4 must be specified in dmatcr2. operation will not be guaranteed if any other value is set. also, the counter which counts the occurrence of four transfers for address reloading is reset by clearing of the dme bit in dmaor or the de bit in chcr2, setting of the transfer end flag (the te bit in chcr2), nmi input, and setting of the ae flag (address error generation in dmac transfer), as well as by a reset and in software standby mode, but sar2, dar2, dmatcr2, and other registers are not reset. consequently, when one of these sources occurs, there is a mixture of initialized counters and uninitialized registers in the dmac, and incorrect operation may result if a restart is executed in this state. therefore, when one of the above sources, other than te setting, occurs during use of the address reload function, sar, dar2, and dmatcr2 settings must be carried out before re- execution. section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 188 of 818 rej09b0273-0500 9.3.12 dma transfer ending conditions the dma transfer ending conditions vary for individual channels ending and for all channels ending together. individual channel ending conditions: there are two ending conditions. a transfer ends when the value of the channel ? s dma transfer count register (tcr) is 0, or when the de bit of the channel ? s chcr is cleared to 0. ? when dmatcr is 0: when the dmatcr value becomes 0 and the corresponding channel's dma transfer ends, the transfer end flag bit (te) is set in the chcr. if the ie (interrupt enable) bit has been set, a dmac interrupt (dei) is requested of the cpu. ? when de of chcr is 0: software can halt a dma transfer by clearing the de bit in the channel ? s chcr. the te bit is not set when this happens. conditions for ending all channels simultaneously: transfers on all channels end when the nmif (nmi flag) bit or ae (address error flag) bit is set to 1 in the dmaor, or when the dme bit in the dmaor is cleared to 0. ? when the nmif or ae bit is set to 1 in dmaor: when an nmi interrupt or dmac address error occurs, the nmif or ae bit is set to 1 in the dmaor and all channels stop their transfers. the dmac obtains the bus rights, and if these flags are set to 1 during execution of a transfer, dmac halts operation when the transfer processing currently being executed ends, and transfers the bus right to the other bus master. consequently, even if the nmif or ae bits are set to 1 during a transfer, the dma source address register (sar), designation address register (dar), and transfer count register (tcr) are all updated. the te bit is not set. to resume the transfers after nmi interrupt or address error processing, clear the appropriate flag bit to 0. to avoid restarting a transfer on a particular channel, clear its de bit to 0. when the processing of a one unit transfer is complete. in a dual address mode direct address transfer, even if an address error occurs or the nmi flag is set during read processing, the transfer will not be halted until after completion of the following write processing. in such a case, sar, dar, and tcr values are updated. in the same manner, the transfer is not halted in dual address mode indirect address transfers until after the final write processing has ended. ? when dme is cleared to 0 in dmaor: clearing the dme bit to 0 in the dmaor aborts the transfers on all channels. the te bit is not set. section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 189 of 818 rej09b0273-0500 9.3.13 dmac access from cpu the space addressed by the dmac is 3-cycle space. therefore, when the cpu becomes the bus master and accesses the dmac, a minimum of three basic clock (clk) cycles are required for one bus cycle. also, since the dmac is located in word space, while a word-size access to the dmac is completed in one bus cycle, a longword-size access is automatically divided into two word accesses, requiring two bus cycles (six basic clock cycles). these two bus cycles are executed consecutively; a different bus cycle is never inserted between the two word accesses. this applies to both write accesses and read accesses. 9.4 examples of use 9.4.1 example of dma transfer between on-chip sci and external memory in this example, on-chip serial communication interface channel 0 (sci0) received data is

source and internal memory is the transfer destination, and the address reload function is on. table 9.9 indicates the transfer conditions and the setting values of each of the registers. section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 191 of 818 rej09b0273-0500 table 9.9 transfer conditions and register set values for transfer between a/d converter and internal

byte interrupt request generation at end of transfer channel priority ranking: 0 > 2 > 3 > 1 dmaor h'0101 when address reload is on, the sar value returns to its initially established value every four transfers. in the above example, when a transfer request is input from the a/d converter, the byte size data is first read in from the h'ffff85f0 register of ad1 and that data is written to the internal address h'ffffe800. because a byte size transfer was performed, the sar and dar values at this point are h'ffff85f1 and h'ffffe801, respectively. also, because this is a burst transfer, the bus rights remain secured, so continuous data transfer is possible. when four transfers are completed, if the address reload is off, execution continues with the fifth and sixth transfers and the sar value continues to increment from h'ffff85f3 to h'ffff85f4 to h'ffff85f5 and so on. however, when the address reload is on, the dmac transfer is halted upon completion of the fourth one and the bus right request signal to the cpu is cleared. at this time, the value stored in sar is not h'ffff85f3 to h'ffff85f4, but h'ffff85f3 to h'ffff85f0, a return to the initially established address. the dar value always continues to be decremented regardless of whether the address reload is on or off. the dmac internal status, due to the above operation after completion of the fourth transfer, is indicated in table 9.10 for both address reload on and off. section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 192 of 818 rej09b0273-0500 table 9.10 dmac internal status item

interrupts not issued not issued transfer request source flag clear executed not executed notes: 1. interrupts are executed until the dmatcr value becomes 0, and if the ie bit of the chcr is set to 1, are issued regardless of whether the address reload is on or off. 2. if transfer request source flag clears are executed until the dmatcr value becomes 0, they are executed regardless of whether the address reload is on or off. 3. designate burst mode when using the address reload function. there are cases where abnormal operation will result if it is executed in cycle steal mode. 4. designate a multiple of four for the tcr value when using the address reload function. there are cases where abnormal operation will result if anything else is designated. to execute transfers after the fifth one when the address reload is on, make the transfer request source issue another transfer request signal. 9.4.4 example of dma transfer between external memory and sci1 send side (indirect address on) in this example, dmac channel 3 is used, an indirect address designated external memory is the transfer source and the sci1 sending side is the transfer destination. table 9.11 indicates the transfer conditions and the setting values of each of the registers. section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 193 of 818 rej09b0273-0500 table 9.11 transfer conditions and

ranking: 0 > 1 > 2 > 3 dmaor h'0001 when indirect address mode is on, the data stored in the address established in sar is not used as the transfer source data. in the case of indirect addressing, the value stored in the sar address is read, then that value is used as the address and the data read from that address is used as the transfer source data, then that data is stored in the address designated by the dar. in the table 9.11 example, when a transfer request from the tdr1 of sci1 is generated, a read of the address located at h'00400000, which is the value set in sar3, is performed first. the data h'00450000 is stored at this h'00400000 address, and the dmac first reads this h'00450000 value. it then uses this read value of h'00450000 as an address and reads the value of h'55 that is stored in the h'00450000 address. it then writes the value h'55 to the address h'ffff81b3 designated by dar3 to complete one indirect address transfer. with indirect addressing, the first executed data read from the address established in sar3 always results in a longword size transfer regardless of the ts0, ts1 bit designations for transfer data size. however, the transfer source address fixed and increment or decrement designations are as according to the sm0, sm1 bits. consequently, despite the fact that the transfer data size designation is byte in this example, the sar3 value at the end of one transfer is h'00400004. the write operation is exactly the same as an ordinary dual address transfer write operation. section 9 direct memory access controller (dmac) rev. 5.00 jan 06, 2006 page 194 of 818 rej09b0273-0500 9.5 cautions on use 1. access is possible regardless of the dma channel control register (chcr0 to chcr3) data size. other than the dma operation register (dmaor) accessing in byte (8 bit) or word (16 bit) units, access all registers in word (16 bit) or longword (32 bit) units. 2. when rewriting the rs0 ? rs3 bits of chcr0 ? chcr3, first clear the de bit to 0 (set the de bit to 0 before doing rewrites with a chcr byte address). 3. when an nmi interrupt is input, the nmif bit of the dmaor is set even when the dmac is not operating. 4. set the dme bit of the dmaor to 0 and make certain that any dmac received transfer request processing has been completed before entering standby mode. 5. do not access the dmac, dtc, bsc, or ubc on-chip peripheral modules from the dmac. 6. when activating the dmac, do the chcr or dmaor setting as the final step. there are instances where abnormal operation will result if any other registers are established last. 7. after the dmatcr count becomes 0 and the dma transfer ends normally, always write a 0 to the tcr, even when executing the maximum number of transfers on the same channel. there are instances where abnormal operation will result if this is not done. 8. designate burst mode as the transfer mode when using the address reload function. there are instances where abnormal operation will result in cycle steal mode. 9. designate a multiple of four for the tcr value when using the address reload function. there are instances where abnormal operation will result if anything else is designated. 10. when detecting external requests by falling edge, maintain the external request pin at high level when performing the dmac establishment. 11. when operating in single address mode, establish an external address as the address. there are instances where abnormal operation will result if an internal address is established. 12. do not access dmac register empty addresses (h'ffff86b2 to h'ffff86bf). operation cannot be guaranteed when empty addresses are accessed. 13. if dmac transfer is aborted by nmi or ae setting, or dme or de2 clearing, during dmac execution with address reload on, the sar2, dar2, and dmatcr2 settings should be made before reexecuting the transfer. the dmac will not operate correctly if this is not done. section 10 advanced

the timer status registers (tsr) are 8-bit registers. the atu has eight tsr registers: two for channel 0, one each for channels 1 and 2, two for channels 3 to 5, one for channels 6 to 9, and one for channel 10. channel abbreviation function 0 tsrah, tsral indicates input capture, interval interrupt, and overflow status. 1 tsrb indicates input capture, compare-match, and overflow status 2tsrc 3 tsrdh, tsrdl indicates input capture, compare-match, and overflow status. 4 5 6 tsre indicates cycle register compare-match status 7 8 9 10 tsrf indicates down-counter underflow status. the tsr registers are 8-bit readable/writable registers containing flags that indicate free-running counter (tcnt) overflow, channel 0 input capture or interval interrupt generation, general register input capture or compare-match, channel 6 to 9 compare-matches, down-counter underflow. each flag is an interrupt source, and issues an interrupt request to the cpu if the interrupt is enabled by the corresponding bit in the timer interrupt enable register (tier). each tsr is initialized to h'00 by a power-on reset, and in hardware standby mode and software standby mode. section 10 advanced timer

5.00 jan 06, 2006 page 283 of 818 rej09b0273-0500 10.3 operation 10.3.1 overview the atu has eleven timers of seven kinds in channels 0 to 10. it also has a built-in prescaler that generates input clocks, and it is possible to generate or select internal clocks of the required frequency independently of circuitry outside the atu. the operation of each channel and the prescaler is outlined below. channel 0 (32-bit dedicated input capture timer): channel 0 has a 32-bit free-running counter (tcnt0) and four 32-bit input capture registers (icr0a to icr0d). tcnt0 is an up- counter that performs free-running operation. the four input capture registers (icr0a to icr0d) can be used for input capture with input from the corresponding external signal input pin (tia0 to tid0) or output compare-match trigger input from channel 1 gr1a. input pin (tia0 to tid0) and gr1a output compare-match trigger selection can be made by setting the trigger selection register (tgsr). channel 0 also has an interval interrupt request register (itvrr). when 1 is set in itve0 to itve3 in itvrr, an interval timer function can be used whereby an interrupt request can be sent to the cpu when the corresponding bit (of bits 10 to 13) in tcnt0 changes to 1. channels 1 and 2: atu channel 1 has a 16-bit free-running counter (tcnt1) and six 16-bit general registers (gr1a to gr1f). tcnt1 is an up-counter that performs free-running operation. the six general registers (gr1a to gr1f) can be used as input capture or output compare-match registers using the corresponding external signal i/o pin (tioa0 to tiof0). use as a one-shot pulse offset function is also possible in combination with atu channel 10 described below. channel 2 has a 16-bit free-running counter (tcnt2) and two 16-bit general registers (gr2a and gr2b). channel 2 can perform the same kind of operations as channel 1, the only difference being in the number of general registers. in addition, channel 1 has a 16-bit dedicated input capture register (osbr) (not provided in channel 2). the tia0 external pin for input to channel 0 can also be used as the osbr trigger input, enabling use of a twin-capture function. section 10 advanced timer unit (atu) rev. 5.00 jan 06, 2006 page 284 of 818 rej09b0273-0500 channels 3, 4, and 5: atu channels 3 and 4 each have a 16-bit free-running counter (tcnt3, tcnt4) and four 16-bit general registers (gr3a to gr3d, gr4a to gr4d). tcnt3 and tcnt4 are up-counters that perform free-running operation. the four general registers (gr3a to gr3d, gr4a to gr4d) each have corresponding external signal i/o pins (tioa3 to tiod3, tioa4 to tiod4, tioa5, tiob5), and can be used as input capture or output compare-match registers. with channels 3 and 4, gr3d and gr4d are automatically designated as cycle registers by setting pwm mode in the timer mode register (tmdr). in pwm mode, the counter is automatically cleared by an output compare-match when the gr3d/gr4d value matches the tcnt3/tcnt4 value. therefore, channels 3 and 4 can each be used as 3-channel pwm timers, with gr3a to gr3c or gr4a to gr4c as the duty registers, and gr3d or gr4d as the cycle register. channel 5 has a 16-bit counter (tcnt5) and two 16-bit general registers (gr5a and gr5b). channel 5 can perform the same kind of operations as channel 3, the only difference being in the number of general registers. in pwm mode, gr5a is designated as the duty register and gr5b as the cycle register. channels 6, 7, 8, and 9 (dedicated pwm timers): atu channels 6 to 9 each have a 16-bit free- running counter (tcnt6 to tcnt9), 16-bit cycle register (cylr6 to cylr9), 16-bit duty register dtr6 to dtr9), and buffer register (bfr6 to bfr9). each of channels 6 to 9 also has an external output pin (to6 to to9), and can be used as a buffered pwm timer. tcnt6 to tcnt9 are up-counters, and 0 is output to the corresponding external output pin when the tcnt value matches the dtr value (when dtr channel 10: atu channel 10 has eight 16-bit down-counters (dcnt10a to dcnt10h), and corresponding external output pins (toa10 to toh10). one-shot pulse output can be performed by setting the dcnt value, starting dcnt operation in the user program and outputting 1 to the external output pin, then halting the count operation when dcnt underflows, and outputting 0 to the external output pin. by coupling the operation with the channel 1 or channel 2 output compare function, offset one- shot pulse output can be performed, whereby a one-shot pulse is generated by starting dcnt section 10 advanced timer unit (atu) rev. 5.00 jan 06, 2006 page 285 of 818 rej09b0273-0500 operation in response to a compare-match signal and outputting 1 to the external output pin, then halting the count operation when dcnt underflows, and outputting 0. prescaler: the atu has a dedicated prescaler with a 2-stage configuration. the first prescaler stage includes a 5-bit prescaler register (pscr1) that allows any scaling factor from 1 to 1/32 to be specified. the first prescaler stage supplies a clock ( 10.3.2 free-running count operation and cyclic count operation the atu channel 0 to 5 free-running counters (tcnt) are all designated as free-running counters immediately after a reset, and start counting up as free-running counters when the corresponding tstr bit is set to 1. when tcnt overflows (channel 0: from h'ffffffff to h'00000000; channels 1 to 5: from h'ffff to h'0000), the ovf bit in the timer status register (tsr) is set to 1. if the ove bit in the corresponding timer interrupt enable register (tier) is set to 1 at this time, an interrupt request is sent to the cpu. after overflowing, tcnt starts counting up again from h'00000000 or h'0000. if the timer start register (tstr) value is cleared to 0 during the count, only the corresponding free-running counter (tcnt) stops counting, and initialization of all tcnt counters and atu registers is not performed. the value at the point at which the tstr value is cleared to 0 continues to be output externally. free-running counter operation is shown in figure 10.11. (for channel 0: h'00000000 to h'ffffffff) time h'ffff h'0000 ovf str bit in tstr figure 10.11 free-running counter operation section 10 advanced timer unit (atu) rev. 5.00 jan 06, 2006 page 286 of 818 rej09b0273-0500 the atu channel 6 to 9 counters (tcnt) all perform cyclic count operations unconditionally. atu channel 3 to 5 free-running counters (tcnt) perform synchronous count operation when 1 is set in bits t3pwm to t5pwm in the timer mode register (tmdr). these free-running counters also perform synchronous count operation if the corresponding cci bit in the timer i/o control register (tior) is set to 1 when bits t3pwm to t5pwm are 0. the relevant tcnt counter is cleared by a compare-match of tcnt with gr3d or gr4d in channel 3 or 4, gr5b in channel 5, or cylr in channels 6 to 9 (counter clear function). in this way, cyclic counting is performed. tcnt starts counting up as a cyclic counter when the corresponding str bit in tstr is set to 1 after the tmdr setting is made. when the count value matches the gr3d, gr4d, gr5b, or cylr value, the corresponding imf3d, imf4d, or imf5b bit in timer status register d (tsrd) (or the cmf bit in tsre for channels 6 to 9) is set to 1, and tcnt is cleared to h'0000 (h'0001 for channels 6 to 9). if the corresponding tier bit is set to 1 at this time, an interrupt request is sent to the cpu. after the compare-match, tcnt starts counting up again from h'0000 (h'0001 for channels 6 to 9). cyclic counter operation is shown in figure 10.12. counter cleared on compare-match time gr3d, gr4d, gr5b, cylr imf3d, imf4d, imf5b, cmf

compare-matches at the corresponding external pin (tioa1 to tiof1, tioa2, tiob2, tioa3 to tiod3, tio4a to tiod4, tioa5, tiob5) by making an output compare-match specification for the timer i/o control registers (tior0 to tior5). a free-running counter (tcnt) starts counting up when 1 is set in the timer status register (tstr). when the desired number is set beforehand in a general register (gr1a to gr1f, gr2a, gr2b, gr3a to gr3d, gr4a to gr4d, gr5a, gr5b), and the counter value matches the corresponding general register, a waveform is output from the corresponding external pin. section 10 advanced timer unit (atu) rev. 5.00 jan 06, 2006 page 287 of 818 rej09b0273-0500 external output value selection and counter clear function (channels 3 to 5 only) specification can be performed with the timer i/o control register (tior). 1 output, 0 output, or toggle output can be selected as the external output value. when the counter clear function is specified, the relevant tcnt is cleared to h'0000 by a compare-match between the corresponding general register and tcnt. if the appropriate interrupt enable register (tier) setting is made, an interrupt request will be sent to the cpu when an output compare-match occurs. an example of free-running counter and output compare-match operation is shown in figure 10.13. in the example in figure 10.13, atu channel 1 is activated, and external

control register (tior), an input capture trigger signal is input from the corresponding external pin (tia0 to tid0, tioa1 to tiof1, tioa2, tiob2, tioa3 to tiod3, tio4a to tiod4, tioa5, tiob5). a free-running counter (tcnt) starts counting up when 1 is set in the timer start register (tstr). when a trigger signal is input from one of the above external pins, the counter value is transferred to the corresponding register (icr0ah/l to icr0dh/l, osbr, gr1a to gr1f, gr2a, gr2b, gr3a to gr3d, gr4a to gr4d, gr5a, gr5b). the detected edge of the external trigger input data can be selected by making a setting in the timer i/o control register (tior). rising-edge, falling-edge, or both-edge detection can be selected. a cpu interrupt request can be issued if the appropriate setting is made in the interrupt enable register (tier). an example of free-running counter and input capture operation is shown in figure 10.14. in the example in figure 10.14, atu channel 1 is activated, and input capture operation is performed with rising-edge detection specified for tioa1 and both-edge detection for tiob1. time counter value tcnt1 h'ffff (32 bits in case of channel 0) h'ffff (32 bits in case

pins (toa10 to toh10) which can be used as one-shot pulse output pins. to generate a one-shot pulse, the one-shot pulse width is set in the down-counter (dcnt), and the corresponding down-count start register (dstr) bit (dst10a to dst10h) is set to 1 by the user program to start the down-count using the clock specified in the timer control register (tcr). when the down-count starts, 1 is output to the corresponding external pin (toa10 to toh10). if the dcnt value is 0, however, the external pin remains at 0 even if dst is set to 1; in this case, a one-shot pulse is not generated, but an interrupt is requested. when the dcnt value underflows, dcnt and the relevant dst bit are automatically cleared to 0, and dcnt stops counting. at the same time, 0 is output to the corresponding external pin. by making the appropriate setting in timer interrupt enable register f (tierf), an interrupt request can be sent to the cpu when the corresponding down-counter (dcnt10a to dcnt10h) reaches 0. it is possible to forcibly output 0 to the output pin during the down-count by clearing dcnt to 0 (since dst cannot be cleared to 0 by the user program). in this case, dcnt and the relevant dst bit are automatically cleared to 0 when the dcnt value underflows, and dcnt stops counting. at the same time, 0 is output to the corresponding external pin. an example of one-shot pulse operation is shown in figure 10.15. in the example in figure 10.15, one-shot pulse widths dataa and datab are set for dcnt10a by the user program, and one-shot pulse output is performed by writing 1 to dst10a.

one-shot pulse operation 10.3.6 offset one-shot pulse function the atu channel 10 down-counters (dcnt) can be coupled with compare-matches between the channel 1 and 2 free-running counters (tcnt) and general registers (gr) by setting bits cn10a to cn10h to 1 in the timer connection register (tcnr). at the same time, the external pins (toa10 to toh10) corresponding to the eight channel 10 down-counters, dcnt10a to dcnt10h, can be used as offset one-shot pulse output pins. setting 1 in timer start register (tstr) bit str1 or str2 starts the up-count by tcnt1 or tcnt2 in channel 1 or 2. when tcnt1 or tcnt2 matches the general register (gr!a to gr1f, gr2a, gr2b) value, the down-count start register (dstr) bit corresponding to bit cn10a to cn10h in tcnr corresponding to gr automatically changes to 1, and the down-count is started. when the down-count starts, 1 is output to the corresponding external pin (toa10 to toh10). if the dcnt value is 0, however, the external pin remains at 0 even if dst is set to 1; in this case, a one-shot pulse is not generated, but an interrupt is requested. when the dcnt value underflows, dcnt and the relevant dst bit are automatically cleared to 0, and dcnt stops counting. at the same time, 0 is output to the corresponding external pin. as long as a count value is set in dcnt section 10 advanced timer unit (atu) rev. 5.00 jan 06, 2006 page 291 of 818 rej09b0273-0500 from the cpu before the next match with the general register, one-shot pulses can be output consecutively. dstr cannot be rewritten while the offset one-shot pulse function is being used. by making the appropriate setting in timer interrupt enable register f (tierf), an interrupt request can be sent to the cpu one clock cycle after the corresponding down-counter (dcnt10a to dcnt10h) reaches 0. it is possible to forcibly output 0 to the output pin during the down-count by clearing dcnt to 0 (since dst cannot be cleared to 0 by the user program). in this case, dcnt and the relevant dst bit are automatically cleared to 0 when the dcnt value underflows, and dcnt stops counting. at the same time, 0 is output to the corresponding external pin. an example of offset one-shot pulse operation is shown in figure 10.16. in the example in figure 10.16, the atu channel 1 free-running counter is started, and offset one- shot pulse output is performed by means of

0 32-bit free-running counter (tcnt0h, tcnt0l). the upper 4 bits (itvad3 to itvad0) are used to start a/d converter sampling, and the lower 4 bits (itve3 to itve0) generate signals to the interrupt controller (intc). for a/d converter activation, an edge sensor is provided for bits 10 to 13 of tcnt0l, and a/d channel 0 sampling is started when the corresponding bit in tcnt0l changes to 1 as a result of setting 1 in one of the upper 4 bits (itvad3 to itvad0) of itvrr. for generation of interrupt signals to the intc, after detection of bits 10 to 13 of tcnt0l by the edge sensor, when the corresponding bit in tcnt0l changes to 1 as a result of setting 1 in one of the lower 4 bits (itve3 to itve0) of itvrr after detection of bits 10 to 13 of tcnt0l by the edge sensor, the corresponding flag (iif0 to iif3) in timer status register tsrah is set to 1 and an interrupt request is sent to intc. the above four interrupt sources have only one interrupt vector address, and therefore when more than one of bits itve3 to itve0 in itvrr is specified, control branches to the same vector when any tcnt0 bit corresponding to one of the specified bits changes to 1. to suppress interrupts to intc, or to prevent a/d sampling from being started, all itvrr bits should be cleared to 0. a schematic diagram of the interval timer is shown in figure 10.17. section 10 advanced timer unit (atu)

and the tcnt1 value to osbr. rising- edge, falling-edge, or both-edge detection can be selected for the tia0 trigger input pin. by making the appropriate setting in the timer interrupt enable register (tier), an interrupt request can be sent to the cpu when input capture occurs. an example of twin-capture operation is shown in figure 10.19. in the example in figure 10.19, twin-capture is started

mode is set unconditionally for atu channels 6 to 9, and also by setting 1 in the corresponding bit (t3pwm to t5pwm) of the atu channel 3 to 5 timer mode registers (tmdr), enabling the counters to be used as pwm timers. in atu channels 6 to 9, when the free-running counter (tcnt) is started, 0 is output to the external pin if the corresponding duty register (dtr6 to dtr9) value is 0, and 1 is output to the external pin if the dtr6 to dtr9 value is 1. when the tcnt count matches the dtr6 to dtr9 value after the up-count is started, 0 is output to the corresponding external pin (unless 100% duty has been set, in which case 1 is output). when the continuing tcnt up-count matches the cycle register (cylr) value, 1 is output to the corresponding external pin (unless 0% duty has been set, in which case 0 is output). at the same time, the counter is cleared. 0% duty is specified by setting dtr to h'0000, and 100% duty by setting dtr section 10 advanced timer unit (atu) rev. 5.00 jan 06,

tcnt9), cycle register (cylr6 to cylr9), duty register (dtr6 to dtr9), and buffer register (bfr6 to bfr9). pwm waveform output by means of counter matches with the cycle register and duty register is performed as described in section 10.3.9, pwm timer function. however, channels 6 to 9 also include a buffer function, whereby the corresponding buffer register value is transferred to the duty register on a match between the cycle register and counter. if the corresponding bit in timer interrupt enable register e (tiere) is set to 1, an interrupt request can be sent to the cpu when the cycle register value and counter value match. an example of buffered pwm operation is shown in figure 10.22. in the example in figure 10.22, h'4000 is set in bfr6, h'a000 in dtr6, and h'f000 in cylr6,

the tcnt input clock timing. to output a waveform with no error in the waveform of the first cycle, the initial value of the duty register (dtr) should be set to h'0000 (in this case, however, the

32-bit access free-running counter 0 (tcnt0) and input capture registers 0a to 0d (icr0a to icr0d) are 32- bit registers. as these registers are connected to the cpu via an internal 16-bit data bus, a read or write (read only, in the case of icr0a to icr0d) is automatically divided into two 16-bit accesses. figure 10.37 shows a read from tcnt0, and figure 10.38 a write to tcnt0. when reading tcnt0, in the first read the tcnt0h (upper 16-bit) value is output to the internal data bus, and at the same time, the tcnt0l (lower 16-bit) value is output to an internal buffer register. then, in the second read, the tcnt0l (lower 16-bit) value held in the internal buffer register is output to the internal data bus. when writing to tcnt0, in the first write the upper 16 bits are output to an internal buffer register. then, in the second write, the lower 16 bits are output to tcnt0l, and at the same time, the upper 16 bits held in the internal buffer register are output to tcnt0h to complete the write. the above method performs simultaneous reading and simultaneous writing of 32-bit data, preventing contention with an up-count. 1st read operation 2nd read operation cpu cpu

will be started. automatic tsr clearing by dmac activation by the atu: when the dmac is activated by the atu, automatic clearing of tsr will not be performed unless an address in the atu ? s i/o space (h'ffff8200 to h'ffff82ff) is set as either the dmac data transfer source address or destination address. if it is wished to set an address outside the atu ? s i/o space for both transfer source and destination, the corresponding bit should be written with 0 after being read while set to 1 from within the interrupt handling routine. interrupt status flag setting/resetting: with tsrf, a 0 write to a bit is invalid only if duplicate events have occurred for the same bit before writing 0 after reading 1 to clear a specific bit. (the duplicate events are accepted.) in order to perform the 0 write, another 1 read is necessary. also, with tsra to tsre, events are not accepted even if duplicate events have occurred for the same bit before a 0 write following a 1 read is performed. section 10 advanced timer unit (atu) rev. 5.00 jan 06, 2006 page 342 of 818 rej09b0273-0500 external output value in software standby mode: in

with the pin function controller (pfc), and setting the corresponding bits to 1 in the pulse output port control register (popcr). when general register 2a (gr2a) in the advanced timer unit (atu) subsequently generates a compare-match signal, 1 is output from the pins set to 1 by bits 7 to 0 in popcr. when general register 2b (gr2b) generates a compare-match signal, 0 is output from the pins set to 1 by bits 15 to 8 in popcr. 0 is output from the output-enabled state until the first compare-match occurs. the advanced pulse controller output operation is shown in figure 11.2. cr port

355 of 818 rej09b0273-0500 section 12 watchdog timer (wdt) 12.1 overview the watchdog timer (wdt) is a 1-channel timer for monitoring system operations. if a system encounters a problem (crashes, for example) and the timer counter overflows without being rewritten correctly by the cpu, an overflow signal ( wdtovf ) is output externally. the wdt can simultaneously generate an internal reset signal for the entire chip. when the watchdog function is not needed, the wdt can be used as an interval timer. in the interval timer operation, an interval timer interrupt is generated at each counter overflow. the wdt is also used in recovering from the standby mode. 12.1.1 features ? works in watchdog timer mode or interval timer mode. ? outputs wdtovf in the watchdog timer mode. when the counter overflows in the watchdog timer mode, overflow signal wdtovf is output externally. you can select whether to reset the chip internally when this happens. either the power-on reset or manual reset signal can be selected as the internal reset signal. ? generates interrupts in the interval timer mode. when the counter overflows, it generates an interval timer interrupt. ? clears standby mode. ? works with eight counter input clocks. section 12 watchdog timer (wdt) rev. 5.00 jan 06, 2006 page 356 of 818 rej09b0273-0500 12.1.2 block diagram figure 12.1 is the block diagram of the wdt. /2 /64

(the tcnt differs from other registers in that it is more difficult to write to. see section 12.2.4, register access, for details.) when the timer enable bit (tme) in the timer control/status register (tcsr) is set to 1, the watchdog timer counter starts counting pulses of an internal clock selected by clock select bits 2 to 0 (cks2 to cks0) in the tcsr. when the value of the tcnt overflows (changes from h'ff to h'00), a watchdog timer overflow signal ( wdtovf ) or interval timer interrupt (iti) is generated, depending on the mode selected in the wt/ it bit of the tcsr. the tcnt is initialized to h'00 by a power-on reset and when the tme bit is cleared to 0. it is not initialized in the standby mode. bit:76543210 initial value:00000000 r/w: r/w r/w r/w r/w r/w r/w r/w r/w section 12 watchdog timer (wdt) rev. 5.00 jan 06, 2006 page 358 of 818 rej09b0273-0500 12.2.2 timer control/status register (tcsr) the timer control/status register (tcsr) is an 8-bit read/write register. (the tcsr differs from other registers in that it is more difficult to write to. see section 12.2.4, register access, for details.) tcsr performs selection of the timer counter (tcnt) input clock and mode. bits 7 to 5 are initialized to 000 by a power-on reset, in hardware standby mode and software standby mode. bits 2 to 0 are initialized to 000 by a power-on reset and in hardware standby mode, but retain their values in the software standby mode. bit:76543210 ovf wt/ it tme ? ? cks2 cks1 cks0 initial value:00011000 r/w: r/(w) * r/w r/w r r r/w r/w r/w note: * only 0 can be written in bit 7 to clear the flag. bit 7?overflow flag (ovf): indicates that the tcnt has overflowed from h'ff to h'00 in the interval timer mode. it is not set in the watchdog timer mode. bit 7: ovf description 0 no overflow of tcnt in interval timer mode (initial value) cleared by reading ovf, then writing 0 in ovf 1 tcnt overflow in the interval timer mode bit 6?timer mode select (wt/ it it it it ): selects whether to use the wdt as a watchdog timer or interval timer. when the tcnt overflows, the wdt either generates an interval timer interrupt (iti) or generates a wdtovf signal, depending on the mode selected. bit 6: wt/ it it it it description 0 interval timer mode: interval timer interrupt request to the cpu when tcnt overflows (initial value) 1 watchdog timer mode: wdtovf signal output externally when tcnt overflows.

tcnt, tcsr, and rstcsr registers differ from other registers in that they are more difficult to write to. the procedures for writing and reading these registers are given below. writing to the tcnt and tcsr: these registers must be written by a word transfer instruction. they cannot be written by byte transfer instructions. the tcnt and tcsr both have the same write address. the write data must be contained in the lower byte of the written word. the upper byte must be h'5a (for the tcnt) or h'a5 (for the tcsr) (figure 12.2). this transfers the write data from the lower byte to the tcnt or tcsr. h'5a h'ffff8610 address: writing to the tcnt 15 8 7 0 write data h'a5 h'ffff8610 address: writing to the tcsr 15 8 7 0 write data figure 12.2 writing to the tcnt and tcsr writing to the rstcsr: the rstcsr must be written by a word access to address h'ffff8612. it cannot be written by byte transfer instructions. procedures for writing 0 in wovf (bit 7) and for writing to rste (bit 6) and rsts (bit 5) are different, as shown in figure 12.3. to write 0 in the wovf bit, the write data must be h'a5 in the upper byte and h'00 in the lower byte. this clears the wovf bit to 0. the rste and rsts bits are not affected. to write to the rste and rsts bits, the upper byte must be h'5a and the lower byte must be the write data. the values of bits 6 and 5 of the lower byte are transferred to the rste and rsts bits, respectively. the wovf bit is not affected. section 12 watchdog timer (wdt) rev. 5.00 jan 06, 2006 page 362 of 818 rej09b0273-0500 h'a5 h'ffff8612 address: writing 0 to the wovf

other registers. use byte transfer instructions. the read addresses are h'ffff8610 for the tcsr, h'ffff8611 for the tcnt, and h'ffff8613 for the rstcsr. 12.3 operation 12.3.1 watchdog timer mode to use the wdt as a watchdog timer, set the wt/ it and tme bits of the tcsr to 1. software must prevent tcnt overflow by rewriting the tcnt value (normally by writing h'00) before overflow occurs. no tcnt overflows will occur while the system is operating normally, but if the tcnt fails to be rewritten and overflows occur due to a system crash or the like, a wdtovf signal is output externally (figure 12.4). the wdtovf signal can be used to reset the system. the wdtovf signal is output for 128 clock cycles. if the rste bit in the rstcsr is set to 1, a signal to reset the chip will be generated internally simultaneous to the wdtovf signal when tcnt overflows. either a power-on reset or a manual reset can be selected by the rsts bit. the internal reset signal is output for 512 clock cycles. when a watchdog overflow reset is generated simultaneously with a reset input at the res pin, the res reset takes priority, and the wovf bit is cleared to 0. the following are not initialized a wdt reset signal: ? pfc (pin function controller) function register ? i/o port register initializing is only possible by external power-on reset. section 12 watchdog timer (wdt) rev. 5.00 jan 06,

the standby mode with an nmi interrupt. when using the standby mode, set the wdt as described below. before transition to the standby mode: the tme bit in the tcsr must be cleared to 0 to stop the watchdog timer counter before it enters the standby mode. the chip cannot enter the standby mode while the tme bit is set to 1. set bits cks2 to cks0 so that the counter overflow interval is equal to or longer than the oscillation settling time. see section 22.3, ac characteristics, for the oscillation settling time. recovery from the standby mode: when an nmi request signal is received in standby mode, the clock oscillator starts running and the watchdog timer starts incrementing at the rate selected by bits cks2 to cks0 before the standby mode was entered. when the tcnt overflows (changes

(sci) 13.1 overview the sh7050 series has a serial communication interface (sci) with three independent channels, both of which possess the same functions. the sci supports both asynchronous and clock synchronous serial communication. it also has a multiprocessor communication function for serial communication among two or more processors. 13.1.1 features ? select asynchronous or clock synchronous as the serial communications mode. ? asynchronous mode: serial data communications are synched by start-stop in character units. the sci can communicate with a universal asynchronous receiver/transmitter (uart), an asynchronous communication interface adapter (acia), or any other chip that employs a standard asynchronous serial communication. it can also communicate with two or more other processors using the multiprocessor communication function. there are twelve selectable serial data communication formats. ? data length: seven or eight bits ? stop bit length: one or two bits ? parity: even, odd, or none ? multiprocessor bit: one or none ? receive error detection: parity, overrun, and framing errors ? break detection: by reading the rxd level directly when a framing error occurs ? clocked synchronous mode: serial data communication is synchronized with a clock signal. the sci can communicate with other chips having a clock synchronous communication function. there is one serial data communication format. ? data length: eight bits ? receive error detection: overrun errors ? full duplex communication: the transmitting and receiving sections are independent, so the sci can transmit and receive simultaneously. both sections use double buffering, so continuous data transfer is possible in both the transmit and receive directions. ? on-chip baud rate generator with selectable bit rates. ? internal or external transmit/receive clock source: baud rate generator (internal) or sck pin (external). section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 370 of 818 rej09b0273-0500 ? four types of interrupts: transmit-data-empty, transmit-end, receive-data-full, and receive- error interrupts are requested independently. the transmit-data-empty and receive-data-full interrupts can start the direct memory access controller (dmac)/data transfer controller (dtc) to transfer data. 13.1.2 block diagram figure 13.1 shows a

rej09b0273-0500 13.2 register descriptions 13.2.1 receive shift register (rsr) the receive shift register (rsr) receives serial data. data input at the rxd pin is loaded into the rsr in the order received, lsb (bit 0) first, converting the data to parallel form. when one byte has been received, it is automatically transferred to the rdr. the cpu cannot read or write the rsr directly. bit:76543210 r/w:???????? 13.2.2 receive data register (rdr) the receive data register (rdr) stores serial receive data. the sci completes the reception of one byte of serial data by moving the received data from the receive shift register (rsr) into the rdr for storage. the rsr is then ready to receive the next data. this double buffering allows the sci to receive data continuously. the cpu can read but not write the rdr. the rdr is initialized to h'00 by a power-on reset, in hardware standby mode and software standby mode. bit:76543210 initial value:00000000 r/w:rrrrrrrr section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 374 of 818 rej09b0273-0500 13.2.3 transmit shift register (tsr) the transmit shift register (tsr) transmits serial data. the sci loads transmit data from the transmit data register (tdr) into the tsr, then transmits the data serially from the txd pin, lsb (bit 0) first. after transmitting one data byte, the sci automatically loads the next transmit data from the tdr into the tsr and starts transmitting again. if the tdre bit of the ssr is 1, however, the sci does not load the tdr contents into the tsr. the cpu cannot read or write the tsr directly. bit:76543210 r/w:???????? 13.2.4 transmit data register (tdr) the transmit data register (tdr) is an 8-bit register that stores data for serial transmission. when the sci detects that the transmit shift register (tsr) is empty, it moves transmit data written in the tdr into the tsr and starts serial transmission. continuous serial transmission is possible by writing the next transmit data in the tdr during serial transmission from the tsr. the cpu can always read and write the tdr. the tdr is initialized to h'ff by a power-on reset, in hardware standby mode and software standby mode. bit:76543210 initial value:11111111 r/w: r/w r/w r/w r/w r/w r/w r/w r/w section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 375 of 818 rej09b0273-0500 13.2.5 serial mode register (smr) the serial mode register (smr) is an 8-bit register that specifies the sci serial communication format and selects the clock source for the baud rate generator. the cpu can always read and write the smr. the smr is initialized to h'00 by a power-on reset, in hardware standby mode and software standby mode. bit:76543210 c/ a chr pe o/ e stop mp cks1 cks0 initial value:00000000 r/w: r/w r/w r/w r/w r/w r/w r/w r/w bit 7?communication mode (c/ a a a a ): selects whether the sci operates in the asynchronous or clock synchronous mode. bit 7: c/ a a a a description 0 asynchronous mode (initial value) 1 clocked synchronous mode bit 6?character length (chr): selects 7-bit or 8-bit data in the asynchronous mode. in the clock synchronous mode, the data length is always eight bits, regardless of the chr setting. bit 6: chr description 0 eight-bit data (initial value) 1 seven-bit data. (when 7-bit data is selected, the msb (bit 7) of the transmit data register is not transmitted.) bit 5?parity enable (pe): selects whether to add a parity bit to transmit data and to check the parity of receive data, in the asynchronous mode. in the clock synchronous mode, a parity bit is neither added nor checked, regardless of the pe setting. bit 5: pe description 0 parity bit not added or checked (initial value) 1 parity bit added and checked. when pe is set to 1, an even or odd parity bit is added to transmit data, depending on the parity mode (o/ e ) setting. receive data parity is checked according to the even/odd (o/ e ) mode setting. section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 376 of 818 rej09b0273-0500 bit 4?parity mode (o/ e e e e ): selects even or odd parity when parity bits are added and checked. the o/ e setting is used only in asynchronous mode and only when the parity enable bit (pe) is set to 1 to enable parity addition and check. the o/ e setting is ignored in the clock synchronous mode, or in the asynchronous mode when parity addition and check is disabled. bit 4: o/ e e e e description 0 even parity (initial value). if even parity is selected, the parity bit is added to transmit data to make an even number of 1s in the transmitted character and parity bit combined. receive data is checked to see if it has an even number of 1s in the received character and parity bit combined. 1 odd parity. if odd parity is selected, the parity bit is added to transmit data to make an odd number of 1s in the transmitted character and parity bit combined. receive data is checked to see if it has an odd number of 1s in the received character and parity bit combined. bit 3?stop bit length (stop): selects one or two bits as the stop bit length in the asynchronous mode. this setting is used only in the asynchronous mode. it is ignored in the clock synchronous mode because no stop bits are added. in receiving, only the first stop bit is checked, regardless of the stop bit setting. if the second stop bit is 1, it is treated as a stop bit, but if the second stop bit is 0, it is treated as the start bit of the next incoming character. bit 3: stop description 0 one stop bit (initial value). in transmitting, a single bit of 1 is added at the end of each transmitted character. 1 two stop bits. in transmitting, two bits of 1 are added at the end of each transmitted character. bit 2?multiprocessor mode (mp): selects multiprocessor format. when multiprocessor format is selected, settings of the parity enable (pe) and parity mode (o/ e ) bits are ignored. the mp bit setting is used only in the asynchronous mode; it is ignored in the clock synchronous mode. for the multiprocessor communication function, see section 13.3.3, multiprocessor communication. bit 2: mp description 0 multiprocessor function disabled (initial value) 1 multiprocessor format selected section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 377 of 818 rej09b0273-0500 bits 1 and 0?clock select 1 and 0 (cks1 and cks0): these bits select the internal clock source of the on-chip baud rate generator. four clock sources are available; , /4, /16, or /64. for further information on the clock source, bit rate register settings, and baud rate, see section 13.2.8, bit rate register. bit 1: cks1 bit 0: cks0 description 00 (initial value) 1 /4 10 /16 1 /64 13.2.6 serial control register (scr) the serial control register (scr) operates the sci transmitter/receiver, selects the serial clock output in the asynchronous mode, enables/disables interrupt requests, and selects the transmit/receive clock source. the cpu can always read and write the scr. the scr is initialized to h'00 by a power-on reset, in hardware standby mode and software standby mode. manual reset does not initialize scr. bit:76543210 tie rie te re mpie teie cke1 cke0 initial value:00000000 r/w: r/w r/w r/w r/w r/w r/w r/w r/w bit 7?transmit interrupt enable (tie): enables or disables the transmit-data-empty interrupt (txi) requested when the transmit data register empty bit (tdre) in the serial status register (ssr) is set to 1 by transfer of serial transmit data from the tdr to the tsr. bit 7: tie description 0 transmit-data-empty interrupt request (txi) is disabled (initial value). the txi interrupt request can be cleared by reading tdre after it has been set to 1, then clearing tdre to 0, or by clearing tie to 0. 1 transmit-data-empty interrupt request (txi) is enabled section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 378 of 818 rej09b0273-0500 bit 6?receive interrupt enable (rie): enables or disables the receive-data-full interrupt (rxi) requested when the receive data register full bit (rdrf) in the serial status register (ssr) is set to 1 by transfer of serial receive data from the rsr to the rdr. it also enables or disables receive- error interrupt (eri) requests. bit 6: rie description 0 receive-data-full interrupt (rxi) and receive-error interrupt (eri) requests are disabled (initial value). rxi and eri interrupt requests can be cleared by reading the rdrf flag or error flag (fer, per, or orer) after it has been set to 1, then clearing the flag to 0, or by clearing rie to 0. 1 receive-data-full interrupt (rxi) and receive-error interrupt (eri) requests are enabled. bit 5?transmit enable (te): enables or disables the sci serial transmitter. bit 5: te description 0 transmitter disabled (initial value). the transmit data register empty bit (tdre) in the serial status register (ssr) is locked at 1. 1 transmitter enabled. serial transmission starts when the transmit data register empty (tdre) bit in the serial status register (ssr) is cleared to 0 after writing of transmit data into the tdr. select the transmit format in the smr before setting te to 1. bit 4?receive enable (re): enables or disables the sci serial receiver. bit 4: re description 0 receiver disabled (initial value). clearing re to 0 does not affect the receive flags (rdrf, fer, per, orer). these flags retain their previous values. 1 receiver enabled. serial reception starts when a start bit is detected in the asynchronous mode, or synchronous clock input is detected in the clock synchronous mode. select the receive format in the smr before setting re to 1. section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 379 of 818 rej09b0273-0500 bit 3?multiprocessor interrupt enable (mpie): enables or disables multiprocessor interrupts. the mpie setting is used only in the asynchronous mode, and only if the multiprocessor mode bit (mp) in the serial mode register (smr) is set to 1 during reception. the mpie setting is ignored in the clock synchronous mode or when the mp bit is cleared to 0. bit 3: mpie description 0 multiprocessor interrupts are disabled (normal receive operation) (initial value). mpie is cleared when the mpie bit is cleared to 0, or the multiprocessor bit (mpb) is set to 1 in receive data. 1 multiprocessor interrupts are enabled. receive-data-full interrupt requests (rxi), receive-error interrupt requests (eri), and setting of the rdrf, fer, and orer status flags in the serial status register (ssr) are disabled until data with the multiprocessor bit set to 1 is received. the sci does not transfer receive data from the rsr to the rdr, does not detect receive errors, and does not set the rdrf, fer, and orer flags in the serial status register (ssr). when it receives data that includes mpb = 1, mpb is set to 1, and the sci automatically clears mpie to 0, generates rxi and eri interrupts (if the tie and rie bits in the scr are set to 1), and allows the fer and orer bits to be set. bit 2?transmit-end interrupt enable (teie): enables or disables the transmit-end interrupt (tei) requested if tdr does not contain valid transmit data when the msb is transmitted. bit 2: teie description 0 transmit-end interrupt (tei) requests are disabled * (initial value) 1 transmit-end interrupt (tei) requests are enabled. * note: the tei request can be cleared by reading the tdre bit in the serial status register (ssr) after it has been set to 1, then clearing tdre to 0 and clearing the transmit end (tend) bit to 0; or by clearing the teie bit to 0. bits 1 and 0?clock enable 1 and 0 (cke1 and cke0): these bits select the sci clock source and enable or disable clock output from the sck pin. depending on the combination of cke1 and cke0, the sck pin can be used for serial clock output, or serial clock input. select the sck pin function by using the pin function controller (pfc). the cke0 setting is valid only in the asynchronous mode, and only when the sci is internally clocked (cke1 = 0). the cke0 setting is ignored in the clock synchronous mode, or when an external clock source is selected (cke1 = 1). select the sci operating mode in the serial mode register (smr) before setting cke1 and cke0. for further details on selection of the sci clock source, see table 13.10 in section 13.3, operation. section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 380 of 818 rej09b0273-0500 bit 1: cke1 bit

13.2.7 serial status register (ssr) the serial status register (ssr) is an 8-bit register containing multiprocessor bit values, and status flags that indicate sci operating status. the cpu can always read and write the ssr, but cannot write 1 in the status flags (tdre, rdrf, orer, per, and fer). these flags can be cleared to 0 only if they have first been read (after being set to 1). bits 2 (tend) and 1 (mpb) are read-only bits that cannot be written. the ssr is initialized to h'84 by a power-on reset, in hardware standby mode and software standby mode. manual reset does not initialize ssr.

13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 381 of 818 rej09b0273-0500 bit 7?transmit data register empty (tdre): indicates that the sci has loaded transmit data from the tdr into the tsr and new serial transmit data can be written in the tdr. bit 7: tdre description 0 tdr contains valid transmit data tdre is cleared to 0 when software reads tdre after it has been set to 1, then writes 0 in tdre or the dmac writes data in tdr 1 tdr does not contain valid transmit data (initial value) tdre is set to 1 when the chip is power-on reset or enters standby mode, the te bit in the serial control register (scr) is cleared to 0, or tdr contents are loaded into tsr, so new data can be written in tdr bit 6?receive data register full (rdrf): indicates that rdr contains received data. bit 6: rdrf description 0 rdr does not contain valid received data (initial value) rdrf is cleared to 0 when the chip is power-on reset or enters standby mode, software reads rdrf after it has been set to 1, then writes 0 in rdrf, or the dmac reads data from rdr 1 rdr contains valid received data rdrf is set to 1 when serial data is received normally and transferred from rsr to rdr note: the rdr and rdrf are not affected by detection of receive errors or by clearing of the re bit to 0 in the serial control register. they retain their previous contents. if rdrf is still set to 1 when reception of the next data ends, an overrun error (orer) occurs and the received data is lost. section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 382 of 818 rej09b0273-0500 bit 5?overrun error (orer): indicates that data reception ended abnormally due to an overrun error. bit 5: orer description 0 receiving is in progress or has ended normally (initial value). clearing the re bit to 0 in the serial control register does not affect the orer bit, which retains its previous value. orer is cleared to 0 when the chip is power-on reset or enters standby mode or software reads orer after it has been set to 1, then writes 0 in orer 1 a receive overrun error occurred. rdr continues to hold the data received before the overrun error, so subsequent receive data is lost. serial receiving cannot continue while orer is set to 1. in the clock synchronous mode, serial transmitting is disabled. orer is set to 1 if reception of the next serial data ends when rdrf is set to 1 bit 4?framing error (fer): indicates that data reception ended abnormally due to a framing error in the asynchronous mode. bit 4: fer description 0 receiving is in progress or has ended normally (initial value). clearing the re bit to 0 in the serial control register does not affect the fer bit, which retains its previous value. fer is cleared to 0 when the chip is power-on reset or enters standby mode or software reads fer after it has been set to 1, then writes 0 in fer 1 a receive framing error occurred. when the stop bit length is two bits, only the first bit is checked to see if it is a 1. the second stop bit is not checked. when a framing error occurs, the sci transfers the receive data into the rdr but does not set rdrf. serial receiving cannot continue while fer is set to 1. in the clock synchronous mode, serial transmitting is also disabled. fer is set to 1 if the stop bit at the end of receive data is checked and found to be 0 section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 383 of 818 rej09b0273-0500 bit 3?parity error (per): indicates that data reception (with parity) ended abnormally due to a parity error in the asynchronous mode. bit 3: per description 0 receiving is in progress or has ended normally (initial value). clearing the re bit to 0 in the serial control register does not affect the per bit, which retains its previous value. per is cleared to 0 when the chip is power-on reset or enters standby mode or software reads per after it has been set to 1, then writes 0 in per 1 a receive parity error occurred. when a parity error occurs, the sci transfers the receive data into the rdr but does not set rdrf. serial receiving cannot continue while per is set to 1. in the clock synchronous mode, serial transmitting is also disabled. per is set to 1 if the number of 1s in receive data, including the parity bit, does not match the even or odd parity setting of the parity mode bit (o/ e ) in the serial mode register (smr) bit 2?transmit end (tend): indicates that when the last bit of a serial character was transmitted, the tdr did not contain valid data, so transmission has ended. tend is a read-only bit and cannot be written. bit 2: tend description 0 transmission is in progress tend is cleared to 0 when software reads tdre after it has been set to 1, then writes 0 in tdre, or the dmac writes data in tdr 1 end of transmission (initial value) tend is set to 1 when the chip is power-on reset or enters standby mode, te is cleared to 0 in the serial control register (scr), or tdre is 1 when the last bit of a one-byte serial character is transmitted. bit 1?multiprocessor bit (mpb): stores the value of the multiprocessor bit in receive data when a multiprocessor format is selected for receiving in the asynchronous mode. the mpb is a read-only bit and cannot be written. bit 1: mpb description 0 multiprocessor bit value in receive data is 0 (initial value). if re is cleared to 0 when a multiprocessor format is selected, the mpb retains its previous value. 1 multiprocessor bit value in receive data is 1 section 13 serial communication interface (sci) rev. 5.00 jan

description 0 multiprocessor bit value in transmit data is 0 (initial value) 1 multiprocessor bit value in transmit data is 1 13.2.8 bit rate register (brr) the bit rate register (brr) is an 8-bit register that, together with the baud rate generator clock source selected by the cks1 and cks0 bits in the serial mode register (smr), determines the serial transmit/receive bit rate. the cpu can always read and write the brr. the brr is initialized to h'ff by a power-on reset, in hardware standby mode and software standby mode. each channel has independent baud rate generator control, so different values can be set in the two channels. bit:76543210 initial value:11111111 r/w: r/w r/w r/w r/w r/w r/w r/w r/w table 13.3 lists examples of brr settings in the asynchronous mode; table 13.4

has an asynchronous mode in which characters are synchronized individually, and a clock synchronous mode in which communication is synchronized with clock pulses. asynchronous/clock synchronous mode and the transmission format are selected in the serial mode register (smr), as shown in table 13.8. the sci clock source is selected by the c/ a bit in the serial mode register (smr) and the cke1 and cke0 bits in the serial control register (scr), as shown in table 13.9. asynchronous mode: ? data length is selectable: seven or eight bits. ? parity and multiprocessor bits are selectable, as well as the stop bit length (one or two bits). these selections determine the transmit/receive format and character length. ? in receiving, it is possible to detect framing errors (fer), parity errors (per), overrun errors (orer), and the break state. ? an internal or external clock can be selected as the sci clock source. ? when an internal clock is selected, the sci operates using the on-chip baud rate generator clock, and can output a clock with a frequency matching the bit rate. ? when an external clock is selected, the external clock input must have a frequency 16 times the bit rate. (the on-chip baud rate generator is not used.) clock synchronous mode: ? the communication format has a fixed 8-bit data length. ? in receiving, it is possible to detect overrun errors (orer). ? an internal or external clock can be selected as the sci clock source. ? when an internal clock is selected, the sci operates using the on-chip baud rate generator clock, and outputs a synchronous clock signal to external devices. ? when an external clock is selected, the sci operates on the input synchronous clock. the on-chip baud rate generator is not used. section 13 serial communication

transmitted or received character begins with a start bit and ends with a stop bit. serial communication is synchronized one character at a time. the transmitting and receiving sections of the sci are independent, so full duplex communication is possible. the transmitter and receiver are both double buffered, so data can be written and read while transmitting and receiving are in progress, enabling continuous transmitting and receiving. figure 13.2 shows the general format of asynchronous serial communication. in asynchronous serial communication, the communication line is normally held in the marking (high) state. the sci monitors the line and starts serial communication when the line goes to the space (low) state, indicating a start bit. one serial character consists of a start bit (low), data (lsb first), parity bit (high or low), and stop bit (high), in that order. when receiving in the asynchronous mode, the sci synchronizes on the falling edge of the start bit. the sci samples each data bit on the eighth pulse of a clock with a frequency 16 times the bit rate. receive data is latched at the center of each bit. 0 d0d1d2d3d4d5d6d7 1 1 0/1 1 1 (lsb) (msb) serial data start bit 1

mpb: multiprocessor bit clock: an internal clock generated by the on-chip baud rate generator or an external clock input from the sck pin can be selected as the sci transmit/receive clock. the clock source is selected by the c/ a bit in the serial mode register (smr) and bits cke1 and cke0 in the serial control register (scr) (table 13.9). section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 398 of 818 rej09b0273-0500 when an external clock is input at the sck pin, it must have a frequency equal to 16 times the desired bit rate. when the sci operates on an internal clock, it can output a clock signal at the sck pin. the frequency of this output clock is equal to the bit rate. the phase is aligned as in figure 13.3 so that the rising edge of the clock occurs at the center of each transmit data bit. 0 d0d1d2d3d4d5d6d70/1 1 1 1 frame figure 13.3 output clock and communication data phase relationship (asynchronous mode) sci initialization (asynchronous mode): before transmitting or receiving, clear the te and re bits to 0 in the serial control register (scr), then initialize the sci as follows. when changing the operation mode or communication format, always clear the te and re bits to 0 before following the procedure given below. clearing te to 0 sets tdre to 1 and initializes the transmit shift register (tsr). clearing re to 0, however, does not initialize the rdrf, per, fer, and orer flags and receive data register (rdr), which retain their previous contents. when an external clock is used, the clock should not be stopped during initialization or subsequent operation. sci operation becomes unreliable if the clock is stopped. figure 13.4 is a sample flowchart for initializing the sci. the procedure is as follows (the steps correspond to the numbers in the flowchart): 1. select the communication format in the serial mode register (smr). 2. write the value corresponding to the bit rate in the bit rate register (brr) unless an external clock is used. 3. select the clock source in the serial control register (scr). leave rie, tie, teie, mpie, te and re cleared to 0. if clock output is selected in asynchronous mode, clock output starts immediately after the setting is made to scr. 4. wait for at least the interval required to transmit or receive one bit, then set te or re in the serial control register (scr) to 1. also set rie, tie, teie and mpie as necessary. setting te or re enables the sci to use the txd or rxd pin. the initial states are the marking transmit state, and the idle receive state (waiting for a start bit). section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 399 of 818 rej09b0273-0500 initialize clear te and re bits to 0 in scr set cke1 and cke0 bits in scr (te and

transmitting serial data, the sci operates as follows: 1. the sci monitors the tdre bit in the ssr. when tdre is cleared to 0, the sci recognizes that the transmit data register (tdr) contains new data, and loads this data from the tdr into the transmit shift register (tsr). 2. after loading the data from the tdr into the tsr, the sci sets the tdre bit to 1 and starts transmitting. if the transmit-data-empty interrupt enable bit (tie) is set to 1 in the scr, the sci requests a transmit-data-empty interrupt (txi) at this time. serial transmit data is transmitted in the following order from the txd pin: a. start bit: one 0 bit is output. b. transmit data: seven or eight bits of data are output, lsb first. c. parity bit or multiprocessor bit: one parity bit (even or odd parity) or one multiprocessor bit is output. formats in which neither a parity bit nor a multiprocessor bit is output can also be selected. d. stop bit: one or two 1 bits (stop bits) are output. e. marking: output of 1 bits continues until the start bit of the next transmit data. 3. the sci checks the tdre bit when it outputs the stop bit. if tdre is 0, the sci loads new data from the tdr into the tsr, outputs the stop bit, then begins serial transmission of the next frame. if tdre is 1, the sci sets the tend bit to 1 in the ssr, outputs the stop bit, then continues output of 1 bits (marking). if the transmit-end interrupt enable bit (teie) in the scr is set to 1, a transmit-end interrupt (tei) is requested. figure 13.6 shows an example of sci transmit operation in the asynchronous mode.

the procedure is as follows (the steps correspond to the numbers in the flowchart). 1. sci initialization: set the rxd pin using the pfc. 2. receive error handling and break detection: if a receive error occurs, read the orer, per, and fer bits of the ssr to identify the error. after executing the necessary error handling, clear orer, per, and fer all to 0. receiving cannot resume if orer, per or fer remain set to 1. when a framing error occurs, the rxd pin can be read to detect the break state. 3. sci status check and receive-data read: read the serial status register (ssr), check that rdrf is set to 1, then read receive data from the receive data register (rdr) and clear rdrf to 0. the rxi interrupt can also be used to determine if the rdrf bit has changed from 0 to 1. 4. continue receiving serial data: read the rdr and rdrf bit and clear rdrf to 0 before the stop bit of the current frame is received. if the dmac is started by a receive-data-full interrupt (rxi) to read rdr, the rdrf bit is cleared automatically so this step is unnecessary. section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 403 of 818 rej09b0273-0500 start reception initialization

receiving, the sci operates as follows: 1. the sci monitors the communication line. when it detects a start bit (0), the sci synchronizes internally and starts receiving. 2. receive data is shifted into the rsr in order from the lsb to the msb. 3. the parity bit and stop bit are received. after receiving these bits, the sci makes the following checks: a. parity check. the number of 1s in the receive data must match the even or odd parity setting of the o/e bit in the smr. b. stop bit check. the stop bit value must be 1. if there are two stop bits, only the first stop bit is checked. c. status check. rdrf must be 0 so that receive data can be loaded from the rsr into the rdr. if the data passes these checks, the sci sets rdrf to 1 and stores the received data in the rdr. if one of the checks fails (receive error), the sci operates as indicated in table 13.11. note: when a receive error occurs, further receiving is disabled. while receiving, the rdrf bit is not set to 1, so be sure to clear the error flags. 4. after setting rdrf to 1, if the receive-data-full interrupt enable bit (rie) is set to 1 in the scr, the sci requests a receive-data-full interrupt (rxi). if one of the error flags (orer, per, or fer) is set to 1 and the receive-data-full interrupt enable bit (rie) in the scr is also set to 1, the sci requests a receive-error interrupt (eri). figure 13.9 shows an

the multiprocessor communication function enables several processors to share a single serial communication line for sending and receiving data. the processors communicate in the asynchronous mode using a format with an additional multiprocessor bit (multiprocessor format). in multiprocessor communication, each receiving processor is addressed by a unique id. a serial communication cycle consists of an id-sending cycle that identifies the receiving processor, and a data-sending cycle. the multiprocessor bit distinguishes id-sending cycles from data-sending cycles. the transmitting processor starts by sending the id of the receiving processor with which it wants to communicate as data with the multiprocessor bit set to 1. next the transmitting processor sends transmit data with the multiprocessor bit cleared to 0. receiving processors skip incoming data until they receive data with the multiprocessor bit set to 1. when they receive data with the multiprocessor bit set to 1, receiving processors compare the data with their ids. the receiving processor with a matching id continues to receive further incoming data. processors with ids not matching the received data skip further incoming data until they again receive data with the multiprocessor bit set to 1. multiple processors can send and receive data in this way. figure 13.10 shows the example of communication among processors using the multiprocessor format. section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 407 of 818 rej09b0273-0500 communication formats: four formats are

transmit data: seven or eight bits are output, lsb first. c. multiprocessor bit: one multiprocessor bit (mpbt value) is output. d. stop bit: one or two 1 bits (stop bits) are output. e. marking: output of 1 bits continues until the start bit of the next transmit data. 3. the sci checks the tdre bit when it outputs the stop bit. if tdre is 0, the sci loads data from the tdr into the tsr, outputs the stop bit, then begins serial transmission of the next frame. if tdre is 1, the sci sets the tend bit in the ssr to 1, outputs the stop bit, then continues output of 1 bits in the marking

the clock synchronous mode, the sci transmits and receives data in synchronization with clock pulses. this mode is suitable for high-speed serial communication. the sci transmitter and receiver are independent, so full duplex communication is possible while sharing the same clock. the transmitter and receiver are also double buffered, so continuous transmitting or receiving is possible by reading or writing data while transmitting or receiving is in progress. figure 13.16 shows the general format in clock synchronous serial communication. section 13 serial communication interface (sci)

of communication data note: * high except in continuous transmitting or receiving. figure 13.16 data format in clock synchronous communication in clock synchronous serial communication, each data bit is output on the communication line from one falling edge of the serial clock to the next. data are guaranteed valid at the rising edge of the serial clock. in each character, the serial data bits are transmitted in order from the lsb (first) to the msb (last). after output of the msb, the communication line remains in the state of the msb. in the clock synchronous mode, the sci transmits or receives data by synchronizing with the falling edge of the synchronization clock. communication format: the data length is fixed at eight bits. no parity bit or multiprocessor bit can be added. clock: an internal clock generated by the on-chip baud rate generator or an external clock input from the sck pin can be selected as the sci transmit/receive clock. the clock source is selected by the c/ a bit in the serial mode register (smr) and bits cke1 and cke0 in the serial control register (scr). see table 13.9. when the sci operates on an internal clock, it outputs the clock signal at the sck pin. eight clock pulses are output per transmitted or received character. when the sci is not transmitting or receiving, the clock signal remains in the high state. note: an overrun error occurs only during the receive operation, and the sync clock is output until the re bit is cleared to 0. when you want to perform a receive operation in one- character units, select external clock for the clock source. sci initialization (clock synchronous mode): before transmitting or receiving, software must clear the te and re bits to 0 in the serial control register (scr), then initialize the sci as follows. when changing the mode or communication format, always clear the te and re bits to 0 before following the procedure given below. clearing te to 0 sets tdre to 1 and initializes the transmit section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 416 of 818 rej09b0273-0500 shift register (tsr). clearing re to 0, however, does not initialize the rdrf, per, fer, and orer flags and receive data register (rdr), which retain their previous contents. figure 13.17 is a sample flowchart for initializing the sci. 1. write the value corresponding to the bit rate in the bit rate register (brr) unless an external clock is used. 2. select the clock source in the serial control register (scr). leave rie, tie, teie, mpie, te, and re cleared to 0. 3. select the communication format in the serial mode register (smr). 4. wait for at least the interval required to transmit or receive one bit, then set te or re in the serial control register (scr) to 1. when selecting the simultaneous transmission and receiving, set te and re bits to 1 simultaneously. also set rie, tie, teie, and mpie. the txd, rxd pins becomes usable in response to the pfc corresponding bits and the te, re bit settings. start of initialization clear te and re bits to 0 in scr 1-bit interval elapsed? set te and re to 1 in scr; set rie, tie, teie, and mpie bits yes no 1 set rie, tie,

new data and loads this data from the tdr into the transmit shift register (tsr). 2. after loading the data from the tdr into the tsr, the sci sets the tdre bit to 1 and starts transmitting. if the transmit-data-empty interrupt enable bit (tie) in the scr is set to 1, the sci requests a transmit-data-empty interrupt (txi) at this time. if clock output mode is selected, the sci outputs eight synchronous clock pulses. if an external clock source is selected, the sci outputs data in synchronization with the input clock. data are output from the txd pin in order from the lsb (bit 0) to the msb (bit 7). 3. the sci checks the tdre bit when it outputs the msb (bit 7). if tdre is 0, the sci loads data from the tdr into the tsr, then begins serial transmission of the next frame. if tdre is 1, the sci sets the tend bit in the ssr to 1, transmits the msb, then holds the transmit data pin (txd) in the msb state. if the transmit-end interrupt enable bit (teie) in the scr is set to 1, a transmit-end interrupt (tei) is requested at this time. 4. after the end of serial transmission, the sck pin is held in the high state. section 13 serial communication interface (sci) rev. 5.00 jan

the clock synchronous mode, make sure that orer, per, and fer are cleared to 0. if per or fer is set to 1, the rdrf bit will not be set and both transmitting and receiving will be disabled. the procedure for receiving serial data is listed below: 1. sci initialization: set the rxd pin using the pfc. 2. receive error handling: if a receive error occurs, read the orer bit in ssr to identify

can be loaded from the rsr into the section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 423 of 818 rej09b0273-0500 rdr. if this check passes, the sci sets rdrf to 1 and stores the received data in the rdr. if the check does not pass (receive error), the sci operates as indicated in table 13.11 and no further transmission or reception is possible. if the error flag is set to 1, the rdrf bit is not set to 1 during reception, even if the rdrf bit is 0 cleared. when restarting reception, be sure to clear the error flag. 3. after setting rdrf to 1, if the receive-data-full

interrupt can also be used to determine if the tdre bit has changed from 0 to 1. 3. receive error handling: if a receive error occurs, read the orer bit in ssr to identify the error. after executing the necessary error processing, clear orer to 0. transmitting/receiving cannot resume if orer remains set to 1. 4. sci status check and receive data read: read the serial status register (ssr), check that rdrf is set to 1, then read receive data from the receive data register (rdr) and clear rdrf to 0. the rxi interrupt can also be used to determine if the rdrf bit has changed from 0 to 1. 5. continue transmitting and receiving serial data: read the rdrf bit and rdr, and clear rdrf to 0 before the frame msb (bit 7) of the current frame is received. also read the tdre bit to check whether it is safe to write (if it reads 1); if so, write data in tdr, then clear tdre to 0 before the msb (bit 7) of the current frame is transmitted. when the dmac or the dtc is started by a transmit-data-empty interrupt request (txi) to write data in tdr, the tdre bit is checked and cleared automatically. when the dmac is started by a receive-data-full interrupt (rxi) to read rdr, the rdrf bit is cleared automatically. note: when selecting the transmission or receiving mode to the simultaneous transmission and receiving mode, clear te and re bits to zero once, then set both of them to 1 simultaneously. section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 424 of 818 rej09b0273-0500 start transmitting/receive initialization read tdre bit in ssr all data

serial communication interface (sci) rev. 5.00 jan 06, 2006 page 425 of 818 rej09b0273-0500 13.4 sci interrupt sources and the dmac the sci has four interrupt sources: transmit-end (tei), receive-error (eri), receive-data-full (rxi), and transmit-data-empty (txi). table 13.12 lists the interrupt sources and indicates their priority. these interrupts can be enabled and disabled by the tie, rie, and teie bits in the serial control register (scr). each interrupt request is sent separately to the interrupt controller. txi is requested when the tdre bit in the ssr is set to 1. txi can start the direct memory access controller (dmac) to transfer data. tdre is automatically cleared to 0 when the dmac writes data in the transmit data register (tdr). rxi is requested when the rdrf bit in the ssr is set to 1. rxi can start the dmac to transfer data. rdrf is automatically cleared to 0 when the dmac reads the receive data register (rdr). eri is requested when the orer, per, or fer bit in the ssr is set to 1. eri cannot start the dmac. tei is requested when the tend bit in the ssr is set to 1. tei cannot start the dmac. where the txi interrupt indicates that transmit data writing is enabled, the tei interrupt indicates that the transmit operation is complete. table 13.12 sci interrupt sources interrupt source description dmac activation priority eri receive error (orer, per, or

rej09b0273-0500 13.5 notes on use sections 13.5.1 through 13.5.9 provide information for using the sci. 13.5.1 tdr write and tdre flags the tdre bit in the serial status register (ssr) is a status flag indicating loading of transmit data from tdr into tsr. the sci sets tdre to 1 when it transfers data from tdr to tsr. data can be written to tdr regardless of the tdre bit status. if new data is written in tdr when tdre is 0, however, the old data stored in tdr will be lost because the data has not yet been transferred to the tsr. before writing transmit data to the tdr, be sure to check that tdre is set to 1. 13.5.2 simultaneous multiple receive errors table 13.13 indicates the state of the ssr status flags when multiple receive errors occur simultaneously. when an overrun error occurs, the rsr contents cannot be transferred to the rdr, so receive data is lost. table 13.13 ssr status flags and transfer of receive data ssr status flags receive error status rdrf orer fer per receive data transfer rsr rdr overrun error 1 1 0 0 x framing error 0 0 1 0 o parity error 0 0 0 1 o overrun error + framing error 1 1 1 0 x overrun error + parity error 1 1 0 1 x framing error + parity error 0 0 1 1 o overrun error + framing error + parity error 1111x note: o = receive data is transferred from rsr to rdr. x = receive data is not transferred from rsr to rdr. section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 427 of 818 rej09b0273-0500 13.5.3 break detection and processing break signals can be detected by reading the rxd pin directly when a framing error (fer) is detected. in the break state, the input from the rxd pin consists of all 0s, so fer is set and the parity error flag (per) may also be set. in the break state, the sci receiver continues to operate, so if the fer bit is cleared to 0, it will be set to 1 again. 13.5.4 sending a break signal the txd pin becomes a general i/o pin with the i/o direction and level determined by the i/o port data register (dr) and pin function controller (pfc) control register (cr). these conditions allow break signals to be sent. the dr value is substituted for the marking status until the pfc is set. consequently, the output port is set to initially output a 1. to send a break in serial transmission, first clear the dr to 0, then establish the txd pin as an output port using the pfc. when te is cleared to 0, the transmission section is initialized regardless of the present transmission status. 13.5.5 receive error flags and transmitter operation (clock synchronous mode only) when a receive error flag (orer, per, or fer) is set to 1, the sci will not start transmitting even if tdre is set to 1. be sure to clear the receive error flags to 0 before starting to transmit. note that clearing re to 0 does not clear the receive error flags. 13.5.6 receive data sampling timing and receive margin in the asynchronous mode in the asynchronous mode, the sci operates on a base clock of 16 times the bit rate frequency. in receiving, the sci synchronizes internally with the falling edge of the start bit, which it samples on the base clock. receive data is latched on the rising edge of the eighth base clock pulse (figure 13.23). section 13 serial communication interface (sci) rev. 5.00 jan 06, 2006 page 428 of 818 rej09b0273-0500 078150781505 internal base clock receive data (rxd)

when using an external clock source for the synchronization clock, update the tdr with the dmac, and then after five system clocks or more elapse, input a transmit clock. if a transmit clock is input in the first four system clocks after the tdr is written, an error may occur (figure 13.24). ?

initial value:00000000 r/w:rrrrrrrr (n = 0 to 15) the a/d converter converts analog input to a 10-bit digital value. the upper 8 bits of this data are stored in the upper byte of the addr corresponding to the selected channel, and the lower 2 bits in the lower byte of that addr. only the most significant 2 bits of the addr lower byte data are valid. table 14.3 shows correspondence between the analog input channels and a/d data registers. section 14 a/d converter rev. 5.00 jan 06, 2006 page 438 of 818 rej09b0273-0500 table 14.3 analog input channels and a/d data registers analog input channel a/d data register analog input channel a/d data register analog input channel a/d data register analog input channel a/d data register an0 addr0 an4 addr4 an8 addr8 an12 addr12 an1 addr1 an5 addr5 an9 addr9 an13 addr13 an2 addr2 an6 addr6 an10 addr10 an14 addr14 an3 addr3 an7 addr7 an11 addr11 an15 addr15 14.2.2 a/d control/status register 0 (adcsr0) a/d control/status register 0 (adcsr0) is an 8-bit readable/writable register whose functions include selection of the a/d conversion mode for a/d0. adcsr0 is initialized to h'00 by a power-on reset, and in hardware standby mode and software standby mode. bit:76543210 adf adie adm1 adm0 ch3 ch2 ch1 ch0 initial value:00000000 r/w: r/(w) * r/w r/w r/w r/w r/w r/w r/w note: * only 0 can be written, to clear the flag. bit 7?a/d end flag (adf): indicates the end of a/d conversion. bit 7: adf description 0 indicates that a/d0 is performing a/d conversion, or is in the idle state. [clearing conditions] ? when adf is read while set to 1, then 0 is written in adf ? when the dmac is activated by adi0 (initial value) 1 indicates that a/d0 has finished a/d conversion, and the digital value has been transferred to addr.

rej09b0273-0500 the operation of the a/d converter after adf is set to 1 differs between single mode and scan mode. in single mode, after the a/d converter transfers the digit value to addr, adf is set to 1 and the a/d converter enters the idle state. in scan mode, after all conversions end within one selected analog group, adf is set to 1 and conversion is continued. for example, in the case of 12-channel scanning, adf is set to 1 immediately after the end of conversion for an0 to an3 (group 0) it is not possible to write 1 to adf. bit 6?a/d interrupt enable (adie): enables or disables the a/d interrupt (adi). to prevent incorrect operation, ensure that the adst bit in a/d control register 0 (adcr0) is cleared to 0 before switching the operating mode. bit 6: adie description 0 a/d

adie bit is 1. adi0 is cleared by clearing adf or adie to 0. bits 5 and 4: a/d mode 1 and 0 (adm1, adm0): these bits select the a/d conversion mode from single mode, 4-channel scan mode, 8-channel scan mode, and 12-channel scan mode. to prevent incorrect operation, ensure that the adst bit in a/d control register 0 (adcr0) is cleared to 0 before switching the operating mode. bit 5: adm1 bit 4:

once on the analog channels selected with bits ch3 to ch0 in adcsr. when adm1 and adm0 are set to 01, 4-channel scan mode is set. in scan mode, a/d conversion is performed continuously on a number of channels. the channels on which a/d conversion is to be performed in scan mode are set with bits ch3 to ch0 in adcsr0. in 4-channel scan mode, conversion is performed continuously on the channels in one of analog groups 0 (an0 to an3), 1 (an4 to an7), or 2 (an8 to an11). when adm1 and adm0 are set to 10, 8-channel scan mode is set. in 8-channel scan mode, conversion is performed continuously on the 8 channels in analog groups 0 (an0 to an3) and 1 (an4 to an7) when adm1 and adm0 are set to 11, 12-channel scan mode is set. in 12-channel scan mode, conversion is performed continuously on the 12 channels in analog groups 0 (an0 to an3), 1 (an4 to an7), and 2 (an8 to an11). for details of the operation in single mode and scan mode, see section 14.4, operation. bits 3 to 0?channel select 3 to 0 (ch3 to ch0): these bits, together with the adm1 and adm0 bits, select the analog input channels. to prevent incorrect operation, ensure that the adst bit in a/d control register 0 (adcr0) is cleared

external triggering of a/d conversion is only enabled when the adst bit is cleared to 0. when external triggering is used, the low-level pulse input to the adtrg pin must be at least 1.5 clock cycles in width. for details, see section 14.4.4, external triggering of a/d conversion. section 14 a/d converter rev. 5.00 jan 06, 2006 page 443 of 818 rej09b0273-0500 bit 6?clock select (cks): selects the a/d conversion time. a/d conversion is executed in a maximum of 266 states when cks is 0, and a maximum of 134 states when 1. to prevent incorrect operation, ensure that the adst bit in a/d control register 0 (adcr0) is cleared to 0 before changing the a/d conversion time. for details, see section 14.4.3, analog input setting and a/d conversion time. bit 6: cks description 0 conversion time =

conversion ends ? scan mode: cleared by writing 0 in adst after confirming that adf in adcsr0 is 1 note that the operation of the adst bit differs between single mode and scan mode. in single mode and scan mode, adst is automatically cleared to 0 when a/d conversion ends on one channel. however, in scan mode, when all conversions have ended for the selected analog inputs, adst remains set to 1 in order to start a/d conversion again for all the channels. therefore, the adst bit must be cleared to 0, stopping a/d conversion, before changing the conversion time or the analog input channel selection. ensure that the adst bit in adcr0 is cleared to 0 before switching the operating mode. also, make sure that a/d conversion is stopped (adst is cleared to 0) before changing a/d interrupt enabling (bit adie in adcsr0), the a/d conversion time (bit cks in adcr0), the operating mode (bits adm1 and adm0 in adscr), or the analog input channel selection (bits ch3 to ch0 in adcsr0). the a/d

registers, but they are connected to the cpu by an 8-bit data bus. therefore, the upper and lower bytes must be read separately. to prevent the data being changed between the reads of the upper and lower bytes of an a/d data register, the lower byte is read via a temporary register (temp). the upper byte can be read directly. data is read from an a/d data register as follows. when the upper byte is read, the upper-byte value is transferred directly to the cpu and the lower-byte value is transferred into temp. next, when the lower byte is read, the temp contents are transferred to the cpu. when performing byte-size reads on an a/d data register, always read the upper byte before the lower byte. it is possible to read only the upper byte, but if only the lower byte is read, incorrect data may be obtained. if a word-size read is performed on an a/d data register, reading is performed in upper byte, lower byte order automatically. figure 14.2 shows the data flow for access to an a/d data register. cpu (h'aa) temp (h'40) addrnl (h'40) addrnh (h'aa) module data bus upper-byte read cpu (h'40) temp (h'40) addrnl (h'40) addrnh (h'aa) bus interface module data bus lower-byte read bus

successive approximations with 10-bit resolution. it has two operating modes: single mode and scan mode. in single mode, conversion is performed once on one specified channel, then ends. in scan mode, a/d conversion continues on one or more specified channels until the adst bit is cleared to 0. 14.4.1 single mode single mode, should be selected when only one a/d conversion on one channel is required. single mode is selected for a/d0 by setting the adm1 and adm0 bits in a/d control/status register 0 (adscr0) to 00, and for a/d1 by clearing the scan mode bit in adcsr1 to 0. when the adst bit (in adcr0 for a/d0, or in adcsr1 for a/d1) is set to 1, a/d conversion is started in single mode. the adst bit remains set to 1 during a/d conversion, and is automatically cleared to 0 when conversion ends. when conversion ends, the adf flag in adcsr is set to 1. if the adie bit in adcsr is also 1, an adi interrupt is requested. to clear the adf flag, first read adf when set to 1, then write 0 in adf. if the dmac is activated by the adi interrupt, adf is cleared automatically. an example of the operation when analog input channel 1 (an1) is selected and a/d conversion is performed in single mode is described next. figure 14.3 shows a timing diagram for this example. 1. single mode is selected (adm1 = adm0 = 0), input channel an1 is selected (ch3 = ch2 = ch1 = 0, ch0 = 1), the a/d interrupt is enabled (adie = 1), and a/d conversion is started (adst = 1). 2. when a/d conversion is completed, the result is transferred to addr1. at the same time the adf flag is set to 1, the adst bit is cleared to 0, and the a/d converter becomes idle. 3. since adf = 1 and adie = 1, an adi interrupt is requested. 4. the a/d interrupt handling routine is started. 5. the routine reads adf set to 1, then writes 0 in adf. 6. the routine reads and processes the conversion result (addr1). 7. execution of the a/d interrupt handling routine ends. after this, if the adst bit is set to 1, a/d conversion starts again and steps 2 to 7 are repeated. section 14 a/d converter rev. 5.00 jan 06, 2006 page 449 of 818 rej09b0273-0500 idle set * set * a/d conver- sion starts set * clear * clear *

inputs in a group of one or more channels. scan mode is selected for a/d0 by setting the adm1 and adm0 bits in a/d control/status register 0 (adscr0) to 01 (4-channel scan mode), 10 8-channel scan mode), or 11 (12-channel scan mode), and for a/d1 by setting the scan bit in a/d control/status register 1 (adcsr1) to 1. when the adst bit is set to 1, a/d conversion is started in scan mode. in scan mode, a/d conversion is performed in low-to-high analog input channel number order (an0, an1 ... an15). the adst bit remains set to 1 until written with 0 by software. when all conversions are completed within one selected analog group, the adf flag in adcsr is set to 1 and a/d conversion us repeated. when adf is set to 1, if the adie bit in adcsr is also 1, an adi interrupt (adi0 or adi1) is requested. to clear the adf flag, first read adf when set to 1, then write 0 in adf. if the dmac is activated by the adi interrupt, adf is cleared automatically. an example of the operation when analog input channels 0 to 2 and 4 to 6 (an0 to an2 and an4 to an6) are selected and a/d conversion is performed in 8-channel scan mode is described in figure 14.4. figure 14.6 shows a timing diagram for this example. 1. 8-channel scan mode is selected (adm1 = 1, adm0 = 0), input channels an0 to an2 and an4 to an6 are selected (ch3 = 0, ch2 = 0, ch1 = 1, ch0 = 0), and a/d conversion is started. 2. when conversion of the first channel (an0) is completed, the result is transferred to addr0. next, conversion of the second channel (an1) starts automatically. 3. conversion proceeds in the same way through the third channel (an2). 4. when conversion is completed for all the channels (an0 to an2) in one selected analog group (analog group 0), the adf flag is set to 1. if the adie bit is also 1, an adi interrupt is requested. 5. conversion of the fourth channel (an4) starts automatically. 6. conversion proceeds in the same way through the sixth channel (an6) 7. steps 2 to 6 are repeated as long as the adst bit remains set to 1. when the adst bit is cleared to 0, a/d conversion stops. after this, if the adst bit is set to 1, a/d conversion starts again from the first channel (an0).

circuit in a/d0 and a/d1. the a/d converter samples the analog input at time t d (a/d conversion start delay time) after the adst bit is set to 1, then starts conversion. figure 14.5 shows the a/d conversion timing. the a/d conversion time (t conv ) includes t d and the analog input sampling time (t spl ). the length of t d is not fixed, since it includes the time required for synchronization of the a/d conversion operation. the total conversion time therefore varies within the ranges shown in table 14.4. in scan mode, the t conv values given in table 14.4 apply to the first conversion. in the second and subsequent conversions, t conv is fixed at 256 states when cks = 0 or 128 states when cks = 1. table 14.4 a/d conversion time (single mode) cks = 0 cks = 1 item symbol min typ max min

externally triggered. to activate the a/d converter with an external trigger, first set the pin functions with the pfc (pin function controller), then set the trge bit to 1 in the a/d control register (adcr). for the a/d0 converter module, also set the extrg bit in the a/d trigger register (adtrgr). when a low-level pulse is input to the adtrg pin after these settings have been made, the a/d converter detects the falling edge of the pulse and sets the adst bit to 1. figure 14.6 shows the timing for external trigger input. the adst bit is set to 1 one state after the a/d converter samples the falling edge on the adtrg pin. the timing from setting of the adst bit until the start of a/d conversion is the same as when 1 is written into the adst bit by software. adtrg pin sampled adtrg

converter module can be activated by an a/d conversion request from the atu ? s channel 0 interval timer. to activate the a/d converter by means of the atu, set the trge bit to 1 in a/d control register 0 (adcr0) and clear the extrg bit to 0 in the a/d trigger register (adtrgr). when an atu channel 0 interval timer a/d conversion request is generated after these settings have been made, the adst bit set to 1. the timing from setting of the adst bit until the start of a/d conversion is the same as when 1 is written into the adst bit by software. 14.4.6 adend output pin when channel 15 is used in scan mode, the conversion timing can be monitored with the adend output pin. after the channel 15 analog voltage has been latched in scan mode, and conversion has started, the adend pin goes high. the adend pin subsequently goes low when channel 15 conversion ends. idle a/d conversion idle idle idle idle idle idle idle idle adend state of channel 12 (an12) state of channel 13 (an13) state

5.00 jan 06, 2006 page 456 of 818 rej09b0273-0500 14.5 interrupt sources and dma transfer requests the a/d converter can generate an a/d conversion end interrupt request (adi0 or adi1) upon completion of a/d conversions. the adi interrupt can be enabled by setting the adie bit in the a/d control/status register (adcsr) to 1, or disabled by clearing the adie bit to 0. the dmac can be activated by an adi interrupt. in this case an interrupt request is not sent to the cpu. when the dmac is activated by an adi interrupt, the adf bit in adcsr is automatically cleared when data is transferred by the dmac. see section 9.4.3, example of dma transfer between a/d converter and internal memory, for an example of this operation. 14.6 usage notes the following points should be noted when using the a/d converter. 1. analog input voltage range the voltage applied to analog input pins during a/d conversion should be in the range av ss ann av ref . 2. relation between av cc , av ss and v cc , v ss when using the a/d converter, set av cc = v cc 10%, and av ss = v ss . when the a/d converter is not used, set av ss = v ss , and do not leave the av cc pin open. 3. av ref input range set av ref = 4.5 v to av cc when the a/d converter is used, and av ref av cc when not used.. if conditions 1 , 2 , and 3 above are not met, the reliability of the device may be adversely affected. 4. notes on board design in board design, digital circuitry and analog circuitry should be as mutually isolated as possible, and layout in which digital circuit signal lines and analog circuit signal lines cross or are in close proximity should be avoided as far as possible. failure to do so may result in incorrect operation of the analog circuitry due to inductance, adversely affecting a/d conversion values. also, digital circuitry must be isolated from the analog input signals (ann), analog reference voltage (av ref ), and analog power supply (av cc ) by the analog ground (av ss ). the av ss should be connected at one point to a stable digital ground (v ss ) on the board. section 14 a/d converter rev. 5.00 jan 06, 2006 page 457 of 818 rej09b0273-0500 5. notes on noise countermeasures a protection circuit connected to prevent damage due to an abnormal voltage such as an excessive surge at the analog input pins (ann) and analog reference voltage (av ref ) should be connected between av cc and av ss as shown in figure 14.8. also, the bypass capacitors connected to av cc and av ref and the filter capacitor connected to ann must be connected to av ss . if a filter capacitor is connected as shown in figure 14.8, the input currents at the analog input pins (ann) are averaged, and so an error may arise. careful consideration is therefore required when deciding the circuit constants. av cc av ref

the system clock ( ). when the str bit of the cmstr is set to 1, the cmcnt begins incrementing with the clock selected by cks1 and cks0. bit 1: cks1 bit 0: cks0 description 00 /8 (initial status) 1 /32 10 /128 1 /512 15.2.3 compare match timer counter (cmcnt) the compare match timer counter (cmcnt) is a 16-bit register used as an upcounter for generating interrupt requests. when an internal clock is selected with the cks1, cks0 bits of the cmcsr register and the str bit of the cmstr is set to 1, the cmcnt begins incrementing with that clock. when the cmcnt value matches that of the compare match timer constant register (cmcor), the cmcnt is cleared to h'0000 and the cmf flag of the cmcsr is set to 1. if the cmie bit of the cmcsr is set to 1 at this time, a compare match interrupt (cmi) is requested. the cmcnt is initialized to h'0000 by a power-on reset and in hardware standby mode and software standby mode. bit: 15 14 13 12 11 10 9 8 initial value:00000000 r/w: r/w

compare match timer constant register (cmcor) the compare match timer constant register (cmcor) is a 16-bit register that sets the compare match period with the cmcnt. the cmcor is initialized to h'ffff by a power-on reset and in hardware standby mode and software standby mode. there is no initializing with manual reset. bit: 15 14 13 12 11 10 9 8 initial value:11111111 r/w: r/w r/w r/w r/w

cmcsr register and the str bit of the cmstr is set to 1, the cmcnt begins incrementing with the selected clock. when the cmcnt counter value matches that of the compare match constant register (cmcor), the cmcnt counter is cleared to h'0000 and the cmf flag of the cmcsr register is set to 1. if the cmie bit of the cmcsr register is set to 1 at this time, a compare match interrupt (cmi) is requested. the cmcnt counter begins counting up again from h'0000. figure 15.2 shows the compare match counter operation. section 15 compare match timer (cmt) rev. 5.00 jan 06, 2006 page 466 of 818

interrupts 15.4.1 interrupt sources and dtc activation the cmt has a compare match interrupt for each channel, with independent vector addresses allocated to each of them. the corresponding interrupt request is output when the interrupt request flag cmf is set to 1 and the interrupt enable bit cmie has also been set to 1. when activating cpu interrupts by interrupt request, the priority between the channels can be changed by using the interrupt controller settings. see section 6, interrupt controller, for details. section 15 compare match timer (cmt) rev. 5.00 jan 06, 2006 page 467 of 818 rej09b0273-0500 15.4.2 compare match flag set timing the cmf bit of the cmcsr register is set to 1 by the compare match signal generated when the cmcor register and the cmcnt counter match. the compare match signal is generated upon the final state of the match (timing at which the cmcnt counter matching count value is updated). consequently, after the cmcor register and the cmcnt counter match, a compare match signal will not be generated until a cmcnt counter input clock occurs. figure 15.4 shows the cmf bit set timing. ck cmcnt input clock cmcnt cmcor compare match signal cmf cmi n

cleared either by writing a 0 to it after reading a 1, or by a clear signal after a dtc transfer. figure 15.5 shows the timing when the cmf bit is cleared by the cpu. t 2 t 1 ck cmf cmcsr write cycle

sections 15.5.1?15.5.3 do not arise during cmt operation. 15.5.1 contention between cmcnt write and compare match if a compare match signal is generated during the t 2 state of the cmcnt counter write cycle, the cmcnt counter clear has priority, so the write to the cmcnt counter is not performed. figure 15.6 shows the timing. t 1 t 2 ck address internal write signal compare match signal cmcnt cmcnt

cycle, the counter write has priority, so no increment of the write data results on the writing side. the byte data on the side not performing the writing is also not incremented, so the contents are

bits, e: 15 bits, f: 12 bits, g: 16 bits), and h is a 16-bit input port. all the port pins are multiplexed as general input/output pins (general input pins in the case of port h) and special function pins. the functions of the multiplex pins are selected by means of the pin function controller (pfc). each port is provided with a data register for storing the pin data. 17.2 port a port a is an

program-verify mode ? erase-verify mode ? programming/erase methods the flash memory is programmed 32 bytes at a time. block erase (in single-block units) can be performed. erasing the entire memory requires erasure of each block in turn. block erasing can be performed as required on 1 kb, 28 kb, and 32 kb blocks. ? programming/erase times the flash memory programming time is 10 ms (typ.) for simultaneous 32-byte programming, equivalent to 300 s (typ.) per byte, and the erase time is 100 ms (typ.). ? reprogramming capability the flash memory can be reprogrammed up to 100 times. ? on-board programming modes there are two modes in which flash memory can be programmed/erased/verified on-board: ? boot mode ? user program mode ? automatic bit rate adjustment with data transfer in boot mode, the sh7050?s bit rate can be automatically adjusted to match the transfer bit rate of the host. ? flash memory emulation in ram flash memory programming can be emulated in real time by overlapping a part of ram onto flash memory. ? protect modes there are two protect modes, hardware and software, which allow protected status to be designated for flash memory program/erase/verify operations

control program must be prepared in the host beforehand. the sci to be used is set to channel asynchronous mode. when a reset-start is executed after the sh7050 pins have been set to boot mode, the boot program built into the sh7050 is started and the programming control program prepared in the host is serially transmitted to the sh7050 via the channel 1 sci. in the sh7050, the programming control program received via the channel 1 sci is written into the programming control program area in on-chip ram. after the transfer is completed, control branches to the start address of the programming control program area and the programming control program execution state is entered (flash memory programming is performed). the transferred programming control program must therefore include coding that follows the programming algorithm given later. the system configuration in boot mode is shown in figure 18.3, and the boot mode execution procedure in figure 18.4. rxd1 txd1 sci1

flash memory a software method, using the cpu, is employed to program and erase flash memory in the on- board programming modes. there are four flash memory operating modes: program mode, erase mode, program-verify mode, and erase-verify mode. transitions to these modes can be made by setting the psu, esu, p, e, pv, and ev bits in flmcr1. the flash memory cannot be read while being programmed or erased. therefore, the program (programming control program) that controls flash memory programming/erasing should be located and executed in on-chip ram or external memory. notes: 1. operation is not guaranteed if setting/resetting of the swe, esu, psu, ev, pv, e, and p bits in flmcr1 is executed by a program in flash memory. 2. when programming or erasing, set fwe to 1 (programming/erasing will not be executed if fwe = 0). 3. programming should be performed in the erased state. do not perform additional programming on previously programmed addresses. 18.7.1 program mode follow the procedure shown in the program/program-verify flowchart in figure 18.7 to write data or programs to flash memory. performing program operations according to this flowchart will enable data or programs to be written to flash memory without subjecting the device to voltage stress or sacrificing program data reliability. programming should be carried out 32 bytes at a time. following the elapse of 10 s or more after the swe bit is set to 1 in flash memory control register 1 (flmcr1), 32-byte program data is stored in the program data area and reprogram data area, and the 32-byte data in the program data area in ram is written consecutively to the program address (the lower 8 bits of the first address written to must be h'00, h'20, h'40, h'60, h'80, h'a0, h'c0, or h'e0). thirty-two consecutive byte data transfers are performed. the program address and program data are latched in the flash memory. a 32-byte data transfer must be performed even if writing fewer than 32 bytes; in this case, h'ff data must be written to the extra addresses. next, the watchdog timer is set to prevent overprogramming in the event of program runaway, etc. set 6.6 ms as the wdt overflow period. after this, preparation for program mode (program setup) is carried out by setting the psu bit in flmcr1, and after the elapse of 50 s or more, the operating mode is switched to program mode by setting the p bit in flmcr1. the time during which the p bit is set is the flash memory programming time. use a fixed 500 s pulse for the write time. section 18 rom (128 kb version) rev. 5.00 jan 06, 2006 page 557 of 818 rej09b0273-0500 18.7.2 program-verify mode in program-verify mode, the data written in program mode is read to check whether it has been correctly written in the flash memory. after the elapse of a given programming time, the programming mode is exited (the p bit in flmcr1 is cleared, then the psun bit is cleared at least 10 s later). the watchdog timer is cleared after the elapse of 10 s or more, and the operating mode is switched to program-verify mode by setting the pv bit in flmcr1. before reading in program-verify mode, a dummy write of h'ff data should be made to the addresses to be read. the dummy write should be executed after the elapse of 4 s or more. when the flash memory is read in this state (verify data is read in 32-bit units), the data at the latched address is read. wait at least 2 s after the dummy write before performing this read operation. next, the written data is compared with the verify data, and reprogram data is computed (see figure 18.7) and transferred to the reprogram data area. after 32 bytes of data have been verified, exit program-verify mode, wait for at least 4 s, then clear the swe bit in flmcr1. if reprogramming is necessary, set program mode again, and repeat the program/program-verify sequence as before. however, ensure that the program/program-verify sequence is not repeated more than 400 times on the same bits. section 18 rom (128

after setting the swe bit to 1 in flash memory control register 1 (flmcr1). next, the watchdog timer is set to prevent overerasing in the event of program runaway, etc. set 6.6 ms as the wdt overflow period. after this, preparation for erase mode (erase setup) is carried out by setting the esu bit in flmcr1, and after the elapse of 200 s or more, the operating mode is switched to erase mode by setting the e bit in flmcr1. the time during which the e bit is set is the flash memory erase time. ensure that the erase time does not exceed 5 ms. note: with flash memory erasing, preprogramming (setting all memory data in the memory to be erased to all ? 0 ? ) is not necessary before starting the erase procedure. 18.7.4 erase-verify mode in erase-verify mode, data is read after memory has been erased to check whether it has been correctly erased. after the elapse of the erase time, erase mode is exited (the e bit in flmcr1 is cleared, then the esu bit is cleared at least 10 s later), the watchdog timer is cleared after the elapse of 10 s or more, and the operating mode is switched to erase-verify mode by setting the ev bit in flmcr1. before reading in erase-verify mode, a dummy write of h'ff data should be made to the addresses to be read. the dummy write should be executed after the elapse of 20 s or more. when the flash memory is read in this state (verify data is read in 32-bit units), the data at the latched address is read. wait at least 2 s after the dummy write before performing this read operation. if the read data has been erased (all ? 1 ? ), a dummy write is performed to the next address, and erase-verify is performed. if the read data has not been erased, set erase mode again, and repeat the erase/erase- verify sequence in the same way. however, ensure that the erase/erase-verify sequence is not repeated more than 60 times. when verification is completed, exit erase-verify mode, and wait for at least 5 s. if erasure has been completed on all the erase blocks, clear the swe bit in flmcr1. if there are any unerased blocks, set 1 bit for the flash memory area to be erased, and repeat the erase/erase-verify sequence in the same way. section 18

program/erase protection, hardware protection and software protection. 18.8.1 hardware protection hardware protection refers to a state in which programming/erasing of flash memory is forcibly disabled or aborted. hardware protection is reset by settings in flash memory control register 1 (flmcr1) and erase block register 1 (ebr1). the flmcr1 and ebr1 settings are retained in the error-protected state. (see table 18.7.) table 18.7 hardware protection functions item description program erase fwe pin protection ? when a low level is input to the fwe pin, flmcr1 and ebr1 are initialized, and the program/erase-protected state is entered. yes yes reset/standby protection ? in a reset (including a wdt overflow reset) and in standby mode, flmcr1 and ebr1 are initialized, and the program/erase-protected state is entered. ? in a reset via the res pin, the reset state is not entered unless the res pin is held low until oscillation stabilizes after powering on. in the case of a reset during operation, hold the res pin low for the res pulse width specified in the ac characteristics section. yes yes section 18 rom (128 kb version) rev. 5.00 jan 06, 2006 page 562 of 818 rej09b0273-0500 18.8.2 software protection software protection can be implemented by setting erase block register 1 (ebr1) and the rams bit in the ram emulation register (ramer). when software protection is in effect, setting the p or e bit in flash memory control register 1 (flmcr1) does not cause a transition to program mode or erase mode. (see table 18.8.) table 18.8 software protection functions item description program erase swe pin protection ? clearing the swe bit to 0 in flmcr1 sets the program/erase-protected state for all blocks. ? (execute in on-chip ram or external memory.) yes yes block specification protection ? erase protection can be set for individual blocks by settings in erase block register 1 (ebr1). ? setting ebr1 to h'00 places all blocks in the erase-protected state. ? yes emulation protection ? setting the rams bit to 1 in the ram emulation register (ramer) places all blocks in the program/erase-protected state. yes yes section 18 rom (128 kb version) rev. 5.00 jan 06, 2006 page 563 of 818 rej09b0273-0500 18.8.3 error protection in error protection, an error is detected when sh7050 runaway occurs during flash memory programming/erasing, or operation is not performed in accordance with the program/erase algorithm, and the program/erase operation is aborted. aborting the program/erase operation prevents damage to the flash memory due to overprogramming or overerasing. if the sh7050 malfunctions during flash memory programming/erasing, the fler bit is set to 1 in flmcr2 and the error protection state is entered. the flmcr1 and ebr1 settings are retained, but program mode or erase mode is aborted at the point at which the error occurred. program mode or erase mode cannot be re-entered by re-setting the p or e bit. however, pv and ev bit setting is enabled, and a transition can be made to verify mode. fler bit setting conditions are as follows: 1. when flash memory is read during programming/erasing (including a vector read or instruction fetch) 2. immediately after exception handling (excluding a reset) during programming/erasing 3. when a sleep instruction (including software standby) is executed during programming/erasing 4. when the bus is released during programming/erasing error protection is released only by a reset and in hardware standby mode.

making a setting in the ram emulation register (ramer) enables part of ram to be overlapped onto the flash memory area so that data to be written to flash memory can be emulated in ram in real time. after the ramer setting has been made, accesses cannot be made from the flash memory area or the ram area overlapping flash memory. emulation can be performed in user mode and user program mode.

for all blocks regardless of the value of ram1 and ram0 (emulation protection). in this state, setting the p or e bit in flash memory control register 1 (flmcr1) will not cause a transition to program mode or erase mode. when actually programming a flash memory area, the rams bit should be cleared to 0. 2. a ram area cannot be erased by execution of software in accordance with the erase algorithm

rej09b0273-0500 18.11.9 notes on memory programming 1. when programming addresses which have previously been programmed, carry out auto- erasing before auto-programming. 2. when performing programming using prom mode on a chip that has been programmed/erased in an on-board programming mode, auto-erasing is recommended before carrying out auto-programming. notes: 1. the flash memory is initially in the erased state when the device is shipped by renesas. for other chips for which the erasure history is unknown, it is recommended that auto- erasing be executed to check and supplement the initialization (erase) level. 2. auto-programming should be performed once only on the same address block. additional programming cannot be performed on previously programmed address blocks. 18.12

features the sh7051 has 256 kbytes of on-chip flash memory. the features of the flash memory are summarized below. ? four flash memory operating modes ? program mode ? erase mode ? program-verify mode ? erase-verify mode ? programming/erase methods the flash memory is programmed 32 bytes at a time. block erase (in single-block units) can be performed. block erasing can be performed as required on 1 kb, 28 kb, and 32 kb blocks. ? programming/erase times the flash memory programming time is 10 ms (typ.) for simultaneous 32-byte programming, equivalent to 300 s (typ.) per byte, and the erase time is 100 ms (typ.). ? reprogramming capability the flash memory can be reprogrammed up to 100 times. ? on-board programming modes there are two modes in which flash memory can be programmed/erased/verified on-board: ? boot mode ? user program mode ? automatic bit rate adjustment with data transfer in boot mode, the sh7050?s bit rate can be automatically adjusted to match the transfer bit rate of the host. ? flash memory emulation in ram flash memory programming can be emulated in real time by overlapping a part of ram onto flash memory. ? protect modes there are two protect modes, hardware and software, which allow protected status to be designated for flash memory program/erase/verify operations ? programmer mode flash memory can be programmed/erased in programmer mode, using a prom programmer, as well as in on-board programming mode. section 19 rom (256 kb version) rev. 5.00 jan 06, 2006 page 586 of 818 rej09b0273-0500 19.2 overview 19.2.1 block

channel asynchronous mode. when a reset-start is executed after the sh7051 pins have been set to boot mode, the boot program built into the sh7051 is started and the programming control program prepared in the host is serially transmitted to the sh7051 via the channel 1 sci. in the sh7051, the programming control program received via the channel 1 sci is written into the programming control program area in on-chip ram. after the transfer is completed, control branches to the start address of the programming control program area and the programming control program execution state is entered (flash memory programming is performed). the transferred programming control program must therefore include coding that follows the programming algorithm given later. the system configuration in boot mode is shown in figure 19.3, and the boot mode execution procedure in figure 19.4. rxd1 txd1 sci1 sh7051 flash memory write data reception verify data transmission host on-chip ram figure

boot mode is initiated, the sh7051 measures the low period of the asynchronous sci communication data (h'00) transmitted continuously from the host. the sci transmit/receive format should be set as follows: 8-bit data, 1 stop bit, no parity. the sh7051 calculates the bit rate of the transmission from the host from the measured low period, and transmits one h'00 byte to the host to indicate the end of bit rate adjustment. the host should confirm that this adjustment end indication (h'00) has been received normally, and transmit one h'55 byte to the sh7051. if reception cannot be performed normally, initiate boot mode again (reset), and repeat the above operations. depending on the host ? s transmission bit rate and the sh7051 ? s system clock frequency, there will be a discrepancy between the bit rates of the host and the sh7051. to ensure correct sci operation, the host ? s transfer bit rate should be set to 4800bps, 9600bps. table 19.6 shows host transfer bit rates and system

flash memory in the on- board programming modes. there are four flash memory operating modes: program mode, erase mode, program-verify mode, and erase-verify mode. transitions to these modes are made by setting the psu1, esu1, p1, e1, pv1, and ev1 bits in flmcr1 for addresses h'00000 to h'1ffff, or the psu2, esu2, p2, e2, pv2, and ev2 bits in flmcr2 for addresses h'20000 to h'3ffff. the flash memory cannot be read while being programmed or erased. therefore, the program (programming control program) that controls flash memory programming/erasing should be located and executed in on-chip ram or external memory. notes: 1. operation is not guaranteed if setting/resetting of the swe, esu1, psu1, ev1, pv1, e1, and p1 bits in flmcr1, or the esu2, psu2, ev2, pv2, e2, and p2 bits in flmcr2, is executed by a program in flash memory. 2. when programming or erasing, set fwe to 1 (programming/erasing will not be executed if fwe = 0). 3. programming should be performed in the erased state. do not perform additional programming on previously programmed addresses. 4. do not program addresses h'00000 to h'1ffff and h'20000 to h'3ffff simultaneously. operation is not guaranteed if this is done. 19.7.1 program mode (n = 1 for addresses h'0000 to h'1ffff, n = 2 for addresses h'20000 to h'3ffff) when writing data or programs to flash memory, the program/program-verify flowchart shown in figure 19.7 should be followed. performing program operations according to this flowchart will enable data or programs to be written to flash memory without subjecting the device to voltage stress or sacrificing program data reliability. programming should be carried out 32 bytes at a time. following the elapse of 10 s or more after the swe bit is set to 1 in flash memory control register 1 (flmcr1), 32-byte program data is stored in the program data area and reprogram data area, and the 32-byte data in the program data area in ram is written consecutively to the program address (the lower 8 bits of the first address written to must be h'00, h'20, h'40, h'60, h'80, h'a0, h'c0, or h'e0). thirty-two consecutive byte data transfers are performed. the program address and program data are latched in the flash memory. a 32-byte data transfer must be performed even if writing fewer than 32 bytes; in this case, h'ff data must be written to the extra addresses. section 19 rom (256 kb

after this, preparation for program mode (program setup) is carried out by setting the psun bit in flmcrn, and after the elapse of 50 s or more, the operating mode is switched to program mode by setting the pn bit in flmcrn. the time during which the pn bit is set is the flash memory programming time. use a fixed 500 s pulse for the write time. 19.7.2 program-verify mode (n = 1 for addresses h'0000 to h'1ffff, n = 2 for addresses h'20000 to h'3ffff) in program-verify mode, the data written in program mode is read to check whether it has been correctly written in the flash memory. after the elapse of a given programming time, the programming mode is exited (the pn bit in flmcrn is cleared, then the psun bit is cleared at least 10 s later). the watchdog timer is cleared after the elapse of 10 s or more, and the operating mode is switched to program-verify mode by setting the pvn bit in flmcrn. before reading in program-verify mode, a dummy write of h'ff data should be made to the addresses to be read. the dummy write should be executed after the elapse of 4 s or more. when the flash memory is read in this state (verify data is read in 32-bit units), the data at the latched address is read. wait at least 2 s after the dummy write before performing this read operation. next, the written data is compared with the verify data, and reprogram data is computed (see figure 19.7) and transferred to the reprogram data area. after 32 bytes of data have been verified, exit program-verify mode, wait for at least 4 s, then clear the swe bit in flmcr1. if reprogramming is necessary, set program mode again, and repeat the program/program-verify sequence as before. however, ensure that the program/program-verify sequence is not repeated more than 400 times on the same bits. section 19 rom (256 kb version) rev. 5.00 jan 06, 2006 page 612 of 818 rej09b0273-0500 set swe-bit of flmcr1 wait 10 s n = 1 m = 0 successively write 32-byte data in rewrite data area in ram to

h'1ffff, n = 2 for addresses h'20000 to h'3ffff) when erasing flash memory, the erase/erase-verify flowchart shown in figure 19.8 should be followed. to perform data or program erasure, set the flash memory area to be erased in erase block register n (ebrn) at least 10 s after setting the swe bit to 1 in flash memory control register 1 (flmcr1). next, the watchdog timer is set to prevent overerasing in the event of program runaway, etc. set 6.6 ms as the wdt overflow period. after this, preparation for erase mode (erase setup) is carried out by setting the esun bit in flmcrn, and after the elapse of 200 s or more, the operating mode is switched to erase mode by setting the en bit in flmcrn. the time during which the en bit is set is the flash memory erase time. ensure that the erase time does not exceed 5 ms. note: with flash memory erasing, preprogramming (setting all memory data in the memory to be erased to all ? 0 ? ) is not necessary before starting the erase procedure. 19.7.4 erase-verify mode (n = 1 for addresses h'0000 to h'1ffff, n = 2 for addresses h'20000 to h'3ffff) in erase-verify mode, data is read after memory has been erased to check whether it has been correctly erased. after the elapse of a the erase time, erase mode is exited (the en bit in flmcrn is cleared, then the esun bit is cleared at least 10 s later), the watchdog timer is cleared after the elapse of 10 s or more, and the operating mode is switched to erase-verify mode by setting the evn bit in flmcrn. before reading in erase-verify mode, a dummy write of h'ff data should be made to the addresses to be read. the dummy write should be executed after the elapse of 20 s or more. when the flash memory is read in this state (verify data is read in 32-bit units), the data at the latched address is read. wait at least 2 s after the dummy write before performing this read operation. if the read data has been erased (all ? 1 ? ), a dummy write is performed to the next address, and erase-verify is performed. the erase-verify operation is carried out on all the erase blocks; the erase block register bit for an erased block should be cleared to prevent excessive application of the erase voltage. when verification is completed, exit erase-verify mode, and wait for at least 5 s. if erasure has been completed on all the erase blocks after completing erase-verify operations on all these blocks, clear the swe bit in flmcr1. if there are any unerased blocks, set erase mode again, and repeat the erase/erase-verify sequence as before. however, ensure that the erase/erase-verify sequence is not repeated more than 60 times. section 19 rom (256 kb version) rev. 5.00 jan 06, 2006 page 614 of 818 rej09b0273-0500 end of erasing start set swe bit in flmcr1 set

hardware protection and software protection. 19.8.1 hardware protection hardware protection refers to a state in which programming/erasing of flash memory is forcibly disabled or aborted. hardware protection is reset by settings in flash memory control register 1 (flmcr1), flash memory control register 2 (flmcr2), erase block register 1 (ebr1), and erase block register 2 (ebr2). the flmcr1, flmcr2, ebr1, and ebr2 settings are retained in the error-protected state. (see table 19.7.) table 19.7 hardware protection functions item description program erase fwe pin protection ? when a low level is input to the fwe pin, flmcr1, flmcr2, ebr1, and ebr2 are initialized, and the program/erase- protected state is entered. yes yes reset/standby protection ? in a reset (including a wdt overflow reset) and in standby mode, flmcr1, flmcr2, ebr1, and ebr2 are initialized, and the program/erase-protected state is entered. ? in a reset via the res pin, the reset state is not entered unless the res pin is held low until oscillation stabilizes after powering on. in the case of a reset during operation, hold the res pin low for the res pulse width specified in the ac characteristics section. yes yes section 19 rom (256 kb version) rev. 5.00 jan 06, 2006 page 616 of 818 rej09b0273-0500 19.8.2 software protection software protection can be implemented by setting erase block register 1 (ebr1), erase block register 2 (ebr2), and the rams bit in the ram emulation register (ramer). when software protection is in effect, setting the p1 or e1 bit in flash memory control register 1 (flmcr1), or the p2 or e2 bit in flash memory control register 2 (flmcr2), does not cause a transition to program mode or erase mode. (see table 19.8.) table 19.8 software protection functions item description program erase swe pin protection ? clearing the swe bit to 0 in flmcr1 sets the program/erase-protected state for all blocks. ? (execute in on-chip ram or external memory.) yes yes block specification protection ? erase protection can be set for individual blocks by settings in erase block register 1 (ebr1) and erase block register 2 (ebr2). ? setting ebr1 and ebr2 to h'00 places all blocks in the erase-protected state. ? yes emulation protection ? setting the rams bit to 1 in the ram emulation register (ramer) places all blocks in the program/erase-protected state. yes yes section 19 rom (256 kb version) rev. 5.00 jan 06, 2006 page 617 of 818 rej09b0273-0500 19.8.3 error protection in error protection, an error is detected when sh7051 runaway occurs during flash memory programming/erasing, or operation is not performed in accordance with the program/erase algorithm, and the program/erase operation is aborted. aborting the program/erase operation prevents damage to the flash memory due to overprogramming or overerasing. if the sh7051 malfunctions during flash memory programming/erasing, the fler bit is set to 1 in flmcr2 and the error protection state is entered. the flmcr1, flmcr2, ebr1, and ebr2 settings are retained, but program mode or erase mode is aborted at the point at which the error occurred. program mode or erase mode cannot be re-entered by re-setting the p1, p2, e1, or e2 bit. however, pv1, pv2, ev1, and ev2 bit setting is enabled, and a transition can be made to verify mode. fler bit setting conditions are as follows: 1. when flash memory is read during programming/erasing (including a vector read or instruction fetch) 2. immediately after exception handling (excluding a reset) during programming/erasing 3. when a sleep instruction (including software standby) is executed during programming/erasing 4. when the bus is released during programming/erasing error protection is released only by a reset and in hardware standby mode. figure 19.9 shows the flash memory state transition diagram. section 19 rom (256 kb version) rev. 5.00 jan 06, 2006 page 618 of 818

1. set bits rams, ram1, and ram0 in ramer to 1, 0, 0, to overlap part of ram onto the area (eb8) for which real-time programming is required. 2. real-time programming is performed using the overlapping ram. 3. after the program data has been confirmed, the rams bit is cleared, releasing ram overlap. 4. the data written in the overlapping ram is written into the flash memory space (eb8). notes: 1. when the rams bit is set to 1, program/erase protection is enabled for all blocks regardless of the value of ram1 and ram0 (emulation protection). in this state, setting the p1 or e1 bit in flash memory control register 1 (flmcr1), or the p2 or e2 bit in flash memory control register 2 (flmcr2), will not cause a transition to program mode or erase mode. when actually programming or erasing a flash memory area, the rams bit should be cleared to 0. 2. a ram area cannot be erased by execution of software in accordance with the erase algorithm while flash memory emulation in ram is being used. section 19 rom (256 kb version) rev. 5.00 jan 06, 2006 page 621 of 818 rej09b0273-0500 19.10 note on flash memory programming/erasing in the on-board programming modes (user mode and user program mode), nmi input should be disabled to give top priority to the program/erase operations including ram emulation). 19.11 flash memory programmer mode programs and data can be written and erased in programmer mode as well as in the on-board programming modes. in programmer mode, flash memory read mode, auto-program mode, auto- erase mode, and status read mode are supported. in auto-program mode, auto-erase mode, and status read mode, a status polling procedure is used, and in status read mode, detailed internal signals are output after execution of an auto-program or

concerning memory programming 1. when programming addresses which have previously been programmed, carry out auto- erasing before auto-programming. 2. when performing programming using prom mode on a chip that has been programmed/erased in an on-board programming mode, auto-erasing is recommended before carrying out auto-programming. notes: 1. the flash memory is initially in the erased state when the device is shipped by renesas. for other chips for which the erasure history is unknown, it is recommended that auto- erasing be executed to check and supplement the initialization (erase) level. 2. auto-programming should be performed once only on the same address block. additional programming cannot be performed on previously programmed address blocks. 19.12 notes when converting the f-ztat

ram. the on-chip ram is linked to the cpu and direct memory access controller (dmac) with a 32-bit data bus (figure 20.1). the cpu can access data in the on-chip ram in 8, 16, or 32 bit widths. the dmac can access 8 or 16 bit widths. on-chip ram data can always be accessed in one state, making the ram ideal for use as a program area, stack area, or data area, which require high-speed access. the contents of the on-chip ram are held in both the sleep and software standby modes. when the rame bit (see below) is cleared to 0, the on-chip ram contents are also held in hardware standby mode. memory area 0 addresses h'fffff800 to h'ffffffff (sh7050) and h'ffff0800 to h'ffffffff (sh7051) are allocated to the on-chip ram. h'fffff800 h'fffff804 h'fffff801 h'fffff805 h'fffff802 h'fffff806

20.2 operation the on-chip ram is controlled by means of the system control register (syscr). when the rame bit in syscr is set to 1, the on-chip ram is enabled. accesses to addresses h'ffffe800?h'ffffffff (sh7050) and h'ffffd800?h'ffffffff (sh7051) are then directed to the on-chip ram. when the rame bit in syscr is cleared to 0, the on-chip ram is not accessed. a read will return an undefined value, and a write is invalid. if a transition is made to hardware standby mode after the rame bit in syscr is cleared to 0, the contents of the on-chip ram are held. for details of syscr, see 21.2.2, system control register (syscr), in section 21, power-down state. section 21 power-down state rev. 5.00 jan 06, 2006 page 641 of 818 rej09b0273-0500 section 21 power-down state 21.1 overview in the power-down state, the cpu functions are halted. this enables a great reduction in power consumption. 21.1.1 power-down states the power-down state is effected by the following three modes: 1. hardware standby mode a transition to hardware standby mode is made according to the input level of the res and hstby pins. in hardware standby mode, all chip functions are halted. this state is exited by means of a power-on reset. 2. software standby mode a transition to software standby mode is made by means of software (a cpu instruction). in software standby mode, all chip functions are halted. this state is exited by means of a power-on reset or an nmi interrupt. 3. sleep mode a transition to sleep mode is made by means of a cpu instruction. in software standby mode, basically only the cpu is halted, and all on-chip peripheral modules operate. this state is exited by means of a power-on reset, interrupt, or dma address error. table 21.1 describes the transition conditions for entering the modes from the program execution state as well as the cpu and peripheral function status in each mode and the procedures for canceling each mode. section 21 power-down

read/write 8-bit register that sets the transition to standby mode, and the port status in standby mode. the sbycr is initialized to h'1f by reset. bit:76543210 ssby hiz ?????? initial value:00011111 r/w:r/wr/wrrrrrr bit 7?standby (ssby): specifies transition to the standby mode. the ssby bit cannot be set to 1 while the watchdog timer is running (when the timer enable bit (tme) of the wdt timer control/status register (tcsr) is set to 1). to enter the standby mode, always halt the wdt by 0 clearing the tme bit, then set the ssby bit. bit 7: ssby description 0 executing sleep instruction puts the lsi into sleep mode (initial value) 1 executing sleep instruction puts the lsi into standby mode bit 6?port high impedance (hiz): in the standby mode, this bit selects whether to set the i/o port pin to high impedance or hold the pin status. the hiz bit cannot be set to 1 when the tme bit of the wdt timer control/status register (tcsr) is set to 1. when making the i/o port pin status high impedance, always clear the tme bit to 0 before setting the hiz bit. bit 6: hiz description 0 holds pin status while in standby mode (initial value) 1 keeps pin at high impedance while in standby mode bits 5?0?reserved: bit 5 always reads as 0. always write 0 to bit 5. bits 4?0 always read as 1. always write 1 to these bits. section 21 power-down state rev. 5.00 jan 06, 2006 page 645 of 818 rej09b0273-0500 21.2.2 system control register (syscr) bit:76543210 ???????rame initial value:00000001 r/w:rrrrrrrr/w the system control register (syscr) is an 8-bit readable/writable register that enables or disables accesses to the on-chip ram. syscr is initialized to h'01 by the rising edge of a power-on reset. bits 7 to 1?reserved: these bits are always read as 0, and should only be written with 0. bit 0?rame enable (rame): selects enabling or disabling of the on-chip ram. when rame is set to 1, on-chip ram is enabled. when rame is cleared to 0, on-chip ram cannot be accessed. in this case, a read or instruction fetch from on-chip ram will return an undefined value, and a write to on-chip ram will be ignored. the initial value of rame is 1. when on-chip ram is disabled by clearing rame to 0, do not place an instruction that attempts to access on-chip ram immediately after the syscr write instruction, as normal access cannot be guaranteed in this case. when on-chip ram is enabled by setting rame to 1, place an syscr read instruction immediately after the syscr write instruction. normal access cannot be guaranteed if an on-chip ram access instruction is placed immediately after the syscr write instruction. bit 0: rame description 0 on-chip ram disabled 1 on-chip ram enabled (initial value) section 21 power-down state rev. 5.00 jan 06, 2006 page 646 of 818 rej09b0273-0500 21.3 hardware standby mode 21.3.1 transition to hardware standby mode the chip enters hardware standby mode when the hstby pin goes low. hardware standby mode reduces power consumption drastically by halting all chip functions. as the transition to hardware standby mode is made by means of external pin input, the transition is made asynchronously, regardless of the current state of the chip, and therefore the chip state prior to the transition is not preserved. however, on-chip ram data is retained as long as the specified voltage is supplied. to retain on-chip ram data, clear the ram enable bit (rame) to 0 in the system control register (syscr) before driving the hstby pin low. see ?pin states? for the pin states in hardware standby mode. 21.3.2 exit from hardware standby mode hardware standby mode is exited by means of the hstby pin and res pin. when hstby is driven high while res is low, the clock oscillator starts running. the res pin should be held low long enough for clock oscillation to stabilize. when res is driven high, power-on reset exception handling is started and a transition is made to the program execution state. 21.3.3 hardware standby mode timing figure 21.1 shows sample pin timings for hardware standby mode. a transition to hardware standby mode is made by driving the hstby pin low after driving the res pin low. hardware standby mode is exited by driving hstby high, waiting for clock oscillation to stabilize, then switching res from low to high. section 21 power-down state rev. 5.00 jan 06, 2006 page 647 of 818 rej09b0273-0500

standby mode to enter the standby mode, set the sby bit to 1 in sbycr, then execute the sleep instruction. the lsi moves from the program execution state to the standby mode. in the standby mode, power consumption is greatly reduced by halting not only the cpu, but the clock and on-chip peripheral modules as well. cpu register contents and on-chip ram data are held as long as the prescribed voltages are applied (when the rame bit in syscr is 0). the register contents of some on-chip peripheral modules are initialized, but some are not (table 21.4). the i/o port status can be selected as held or high impedance by the port high impedance bit (hiz) of the sbycr. for pin status other than for the i/o port, refer to appendix b, pin states. section 21 power-down state rev. 5.00 jan 06,

rej09b0273-0500 21.4.2 canceling the software standby mode the standby mode is canceled by an nmi interrupt, a power-on reset, or a manual reset. cancellation by an nmi: clock oscillation starts when a rising edge or falling edge (selected by the nmi edge select bit (nmie) of the interrupt control register (icr) of the intc) is detected in the nmi signal. this clock is supplied only to the watchdog timer. a wdt overflow occurs if the time established by the clock select bits (cks2?cks0) in the tcsr of the wdt elapses before transition to the standby mode. the occurrence of this overflow is used to indicate that the clock has stabilized, so the clock is supplied to the entire chip, the standby mode is canceled, and nmi exception processing begins. when canceling standby mode with nmi interrupts, set the cks2?cks0 bits so that the wdt overflow period is longer than the oscillation stabilization time. when canceling standby mode with an nmi pin set for falling edge, be sure that the nmi pin level upon entering standby (when the clock is halted) is high level, and that the nmi pin level upon returning from standby (when the clock starts after oscillation stabilization) is low level. when canceling standby mode with an nmi pin set for rising edge, be sure that the nmi pin level upon entering standby (when the clock is halted) is low level, and that the nmi pin level upon returning from standby (when the clock starts after oscillation stabilization) is high level. cancellation by a power-on reset: a power-on reset caused by setting the res pin to low level cancels the standby mode. section 21 power-down state rev. 5.00 jan 06, 2006 page 650 of 818 rej09b0273-0500 21.4.3 software standby mode application example this example describes a transition to standby mode on the falling edge of an nmi signal, and a cancellation on the rising edge of the nmi signal. the timing is shown in figure 21.2. when the nmi pin is changed from high to low level while the nmi edge select bit (nmie) of the icr is set to 0 (falling edge detection), the nmi interrupt is accepted. when the nmie bit is set to 1 (rising edge detection) by an nmi exception service routine, the standby bit (sby) of the sbycr is set to 1, and a sleep instruction is executed, standby mode is entered. thereafter, standby mode is canceled when the nmi pin is changed from low to high level. oscillator ck

mode executing the sleep instruction when the sby bit of sbycr is 0 causes a transition from the program execution state to the sleep mode. although the cpu halts immediately after executing the sleep instruction, the contents of its internal registers remain unchanged. the on-chip peripheral modules continue to run during the sleep mode. 21.5.2 canceling sleep mode cancellation by an interrupt: when an interrupt occurs, the sleep mode is canceled and interrupt exception processing is executed. the sleep mode is not canceled if the interrupt cannot be accepted because its priority level is equal to or less than the mask level set in the cpu?s status register (sr) or if an interrupt by an on-chip peripheral module is disabled at the peripheral module. cancellation by a dmac address error: if a dmac address error occurs, the sleep mode is canceled and dmac address error exception processing is executed. cancellation by a power-on reset: a power-on reset resulting from setting the res pin to low level cancels the sleep mode. section 21 power-down state rev. 5.00 jan 06, 2006 page 652 of 818 rej09b0273-0500 section 22 electrical characteristics rev. 5.00 jan 06, 2006 page 653 of
