FUNCTION OUTLINE 2.1 Program Control Unit This unit is used to execute instructions, and control branching, loops, interrupts, the clock, and the standby mode of the DSP. 2.1.1 CPU control A three-stage pipeline architecture is employed and almost all the instructions, except some instructions such as branch instructions, are executed in one system clock. 2.1.2 Interrupt control Interrupt requests input from external pins (INT1 through INT4) or generated by the internal peripherals (serial interface and host interface) are serviced. Multiple interrupts are also supported. 2.1.3 Loop control task A loop function without any hardware overhead is provided. A loop stack with four levels is provided to support multiple loops. 2.1.4 PC stack A 15-level PC stack that stores the program counter supports multiple interrupts and subroutine calls. 2.1.5 PLL A PLL is provided as a clock generator that can multiply or divide an external clock input to supply an operating clock to the DSP. The multiplication and division ratio are set as follows: * PD77110: A multiple of x1 to x8 is specified by an external pin (division ratio is fixed). * PD77111 and 77112: A multiple of x1 to x16 or a division ratio of 1/1 to 1/16 can be set by a mask option. Two standby modes are available for lowering the power consumption while the DSP is not in use. * HALT mode : Set by execution of the HALT instruction. The current consumption drops to several mA. The normal operation mode is recovered by an interrupt or hardware reset. * STOP mode: Set by execution of the STOP instruction. The current consumption drops to several 10 A. The normal operation mode is recovered by hardware reset or WAKEUP pin Note If the WAKEUP function is activated by mask option 2.1.6 Instruction memory The capacity and type of the memory differ depending on the model of the DSP. 64 words of the instruction RAM are allocated to interrupt vectors. A boot-up ROM that boots up the instruction RAM is provided, and the instruction RAM can be initialized or rewritten by self boot (boot from the internal data ROM or external data space) or host boot (boot via host interface). * PD77110: 35.5K-word RAM * PD77111, 77112: 1K-word RAM and 31.75K-word ROM Note The interrupt of each interrupt source can be enabled or disabled. . 20 Data Sheet U12801EJ4V0DS00 PD77110, 77111, 77112 2.2 Arithmetic Unit This unit performs multiplication, addition, logical operations, and shift, and consists of a 40-bit multiply accumulator, 40-bit data ALU, 40-bit barrel shifter, and eight 40-bit general-purpose registers. 2.2.1 General-purpose registers (R0 through R7) These eight 40-bit registers are used to input/output data for arithmetic operations, and load or store data from/to data memory. A general-purpose register (R0 to R7) is made up of three parts: R0L through R7L (bits 15 through 0), R0H through R7H (bits 31 through 16), and R0E through R7E (bits 39 through 32). Depending on the type of operation, RnL, RnH, and RnE are used as one register or in different combinations. 2.2.2 Multiply accumulator (MAC) The MAC multiplies two 16-bit values, and adds or subtracts the multiplication result from one 40-bit value, and outputs a 40-bit value. The MAC is provided with a shifter (MSFT: MAC ShiFTer) at the stage preceding the input stage. This shifter can arithmetically shift the 40-bit value to be added to or subtracted from the multiplication result 1 or 16 bits to the right . 2.2.3 Arithmetic logic unit (ALU) This unit inputs one or two 40-bit values, executes an arithmetic or logical operation, and outputs a 40-bit value. 2.2.4 Barrel shifter (BSFT: Barrel ShiFTer) The barrel shifter inputs a 40-bit value, shifts it to the left or right by any number of bits, and outputs a 40-bit value. The data may be arithmetically shifted to the right shifted to the right, in which case the data is sign-extended, or logically shifted to the right, in which case 0 is inserted from the MSB. Data Sheet U12801EJ4V0DS00 21 PD77110, 77111, 77112 2.3 Data Memory Unit The data memory unit consists of two banks of data memory and two data addressing units. 2.3.1 Data memory The capacity and type of the memory differ depending on the model of the DSP. All DSPs have two banks of data memory (X data memory and Y data memory). A 64-word peripheral area is assigned in the data memory space. * PD77110: RAM of 24K words x 2 banks * PD77111, 77112: RAM of 3K words x 2 banks and ROM of 16K words x 2 banks In addition, some models have an external data memory interface so that the external memory can be expanded. * PD77110: External data memory of 32K words x 2 banks * PD77112: External data memory of 16K words x 2 banks 2.3.2 Data addressing unit An independent data addressing unit is provided for each of the X data memory and Y data memory spaces. Each data addressing unit has four data pointers (DPn), four index registers (DNn), one modulo register (DMX or DMY), and an address ALU. 2.4 Peripheral Units A serial interface, host interface, general-purpose I/O port, and wait cycle register are provided. All these internal peripherals are mapped to the X data memory and Y data memory spaces, and are accessed from program as memory-mapped I/Os. 2.4.1 Serial interface (SIO) Two serial interfaces are provided. These serial interfaces have the following features: * Serial clock : Supplied from external source to each interface. The same clock is used for input and output on the interface. * Frame length: 8 or 16 bits, and MSB or LSB first selectable for each interface and input or output * Handshake : Handshaking with external devices is implemented with a dedicated status signal. With the internal units, polling, wait, or interrupt are used. 2.4.2 Host interface (HIO) This is an 8-bit parallel port that inputs data from or outputs data to an external host CPU or DMA controller. In the DSP, a 16-bit register is mapped to memory for input data, output data, and status. Handshaking with an external device is implemented by using a dedicated status signal. Handshaking with internal units is achieved by means of polling, wait, or interrupts. 2.4.3 General-purpose I/O port (PIO) This is a 4-bit I/O port that can be set in the input or output mode in 1-bit units. 22 Data Sheet U12801EJ4V0DS00 PD77110, 77111, 77112 2.4.4 Wait cycle register The number of wait cycles to be inserted when the external data memory area is accessed can be specified in advance by using a register (DWTR) Note . The number of wait cycles that can be set is 1, 3, or 7. Note This function is not available on the PD77111 because this DSP does not have an external data area. 3. CLOCK GENERATOR The clock generator generates an internal system clock based on the external clock input from the CLKIN pin and supplies the generated clock to the internal units of the DSP. For details of how to set the PLL multiple, refer to 4.2 Initializing PLL, 8.1 Clock Control Options, and 8.3.1 Settings related to clock control. Stop mode Halt mode CLKIN PLL control circuit xm Output divider /n Halt divider /l Internal system clock CLKOUT 4. RESET FUNCTION When a low level of a specified width is input to the RESET pin, the device is initialized. 4.1 Hardware Reset If the RESET pin is asserted active (low level) for a specified period, the internal circuitry of the DSP is initialized. If the RESET pin is then deasserted inactive (high level), boot processing of the instruction RAM is performed according to the status of the port pins (P0 and P1). After boot processing, processing is executed starting from the instruction at address 0x200 of instruction memory (reset entry). On power application, the RESET pin must be asserted active (low level) after 4 input clocks have been input with the RESET pin in the inactive status (high level), after the supply voltage has reached the level of the operating voltage. In other words, no power-ON reset function is available. On power application, the PLL must be initialized. Data Sheet U12801EJ4V0DS00 23 PD77110, 77111, 77112 4.2 Initializing PLL Initializing the PLL starts from the 1024th input clock after the RESET pin has been asserted active (low level). Initialization takes 1024 clocks and it takes the PLL 100 s to be locked. After that, the DSP operates with the set value of the PLL specified by a mask option (PD77111 or 77112) or an external pin (PD77110) when the RESET pin is deasserted inactive (high level). After initializing the PLL, be sure to execute boot-up processing to re-initialize the internal RAM. To initialize the PLL, the internal memory contents and register status of the DSP are not retained. If the RESET pin is deasserted inactive before the PLL initialization mode is set, the DSP is normally reset (the PLL is not initialized). CLKIN 1 RESET 1024 2048 Approx. 100 s PLL lock time PLL initialization (internal status) PLL initialization mode Caution Do not deassert the RESET signal inactive in the PLL initialization mode and during PLL lock period. 5. FUNCTIONS OF BOOT-UP ROM To rewrite the contents of the instruction memory on power application or from program, boot up the instruction RAM by using the internal boot-up ROM. The PD77110 has a function to verify the contents of the internal instruction RAM in the boot-up ROM. 5.1 Boot at Reset After hardware reset has been cleared, the boot program first reads the general-purpose I/O ports P0 and P1 and, depending on their bit pattern, determines the boot mode (self boot or host boot). After boot processing, processing is executed starting from the instruction at address 0x200 (reset entry) of the instruction memory. The pins (P0 and P1) that specify the boot mode must be kept stable for the duration of 3 clocks before and for the duration of 12 clocks after reset has been cleared (the clock is input from CLKIN). P1 0 0 1 1 P0 0 1 1 0 Boot Mode Does not execute boot but branches to address 0x200 Note . Executes host boot and then branches to address 0x200. Executes self boot and then branches to address 0x200. Setting prohibited Note This setting is used when the DSP must be reset to recover from the standby mode after reset boot has been executed once. 24 Data Sheet U12801EJ4V0DS00 PD77110, 77111, 77112 5.1.1 Self boot The boot-up ROM transfers the instruction code stored in the data memory space to the instruction RAM, based on the boot parameter written to address 0x4000 of the Y data memory. Generally, with a mask ROM model (PD77111 or 77112), this function is implemented by storing the instructions to be booted in the data ROM. In addition, the instructions to be booted can be also stored in an external data area in the form of flash ROM, and self boot can be executed from this external data area. With the PD77110, the value of address 0x4000 of the Y data memory is undefined on power application, because this address is in RAM. Therefore, with the PD77110, the self boot mode cannot be selected on power application, and host boot must be executed. This also applies when the PLL is initialized. By writing a boot parameter to address 0x4000 or those that follow of the Y data memory, self boot can be executed when the RESET signal is subsequently input (except the reset that initializes the PLL). In this case, however, the instructions to be booted are only those at address 0x0200 through 0x0FFF of the instruction RAM. 5.1.2 Host boot In this boot mode, a boot parameter and instruction code are obtained via the host interface, and transferred to the instruction RAM. With the PD77110, the host boot mode is used on power application. The boot instruction area is the instruction RAM from addresses 0x0200 through 0x0FFF. To boot up the instruction RAM from 0x4000 through 0xBFFF, host reboot is used. 5.2 Reboot By calling the next reboot entry from the program, the contents of the instruction RAM can be rewritten. In particular, the PD77110 has a reboot function that boots up the instruction RAM from 0x4000 through 0xBFFF. Reboot Mode Self boot X memory Word reboot Byte reboot Y memory Word reboot Byte reboot Host boot Host reboot Entry Address 0x2 0x4 0x1 0x3 0x6 (PD77110) 0x5 (PD77111, 77112) 5.2.1 Self reboot The instruction codes stored in the data memory are transferred to the instruction RAM. This boot mode cannot be used with the PD77110. Set the following parameters and call the entry address of the corresponding reboot mode to execute self reboot. * R7L : Number of instruction steps for rebooting * DP3: First address of X memory in which instruction codes are stored (in the case of reboot from X memory), or first address of the instruction memory to be loaded (in the case of reboot from Y memory) * DP7: First address of instruction memory to be loaded (in the case of reboot from X memory), or first address of X memory in which instruction codes are stored (in the case of reboot from Y memory) Data Sheet U12801EJ4V0DS00 25 PD77110, 77111, 77112 5.2.2 Host reboot An instruction code is obtained via the host interface and transferred to the instruction RAM. With the PD77110, the host reboot mode is used to boot up the instruction RAM from addresses 0x4000 through 0xBFFF. Areas 0x0200 through 0x0FFF and 0x4000 through 0xBFFF cannot be rebooted all at once. The entry address of the PD77110 is 0x6, and that of the PD77111 and 77112 is 0x5. Host reboot is executed by calling this address after setting the following parameter: * R7L : Number of instruction steps for rebooting * DP3: First address of instruction memory to be loaded 5.3 Signature Operation The PD77110 has a signature operation function so that the contents of the internal instruction RAM can be verified. The signature operation performs a specific arithmetic operation on the data in the instruction RAM booted up, and returns the result to a register. Perform the signature operation in advance on the device when it is operating normally, and repeat the signature operation later to check whether the data in RAM is correct by comparing the operation result with the previous result. If the results are identical, there is no problem. The entry address is 0x9. Execute the operation by calling this address after setting the following parameter. Note that the operation cannot be performed on the areas 0x0200 through 0x0FFF and 0x4000 through 0xBFFF at the same time. The operation result is stored in register R7. * R7L: Number of instruction steps for operation * DP3: First address of instruction memory for operation 6. STANDBY MODES Two standby modes are available. By executing the corresponding instruction, each mode is set and the power consumption can be reduced. 6.1 HALT Mode To set this mode, execute the HALT instruction. In this mode, functions other than clock circuit and PLL are stopped to reduce the current consumption. To release the HALT mode, use an interrupt or hardware reset. When releasing the HALT mode using an interrupt, the contents of the internal registers and memory are retained. It takes several 10 system clocks to release the HALT mode when the HALT mode is released using an interrupt. In the HALT Mode, the clock circuit of the PD77111 family supplies the following clock as the internal system clock. The clock output from the CLKOUT pin is as follows. The clock output from the CLKOUT pin, however, has a high-level width that is equivalent to 1 cycle of the normal operation (i.e., the duty factor is not 50%). * PD77110: 1/8 of internal system clock * PD77111, 77112: 1/l of internal system clock (l = integer from 1 to 16, specified by mask option) 26 Data Sheet U12801EJ4V0DS00 PD77110, 77111, 77112 6.2 STOP Mode To set this mode, execute the STOP instruction. In this mode, all the functions, including the clock circuit and PLL, are stopped and the power consumption is minimized with only leakage current flowing. To release the STOP mode, use hardware reset or WAKEUP pin. When releasing the STOP mode by using the WAKEUP pin, the contents of the internal registers and memory are retained, but it takes several 100 s to release the mode. The WAKEUP pin is multiplexed with the INT4 pin. Usually, this pin functions as an interrupt pin, but functions as the WAKEUP pin when it is asserted active in the STOP mode. Whether the WAKEUP pin is used to release the STOP mode is selected by mask option. For details, refer to 8.2 WAKEUP Function and 8.3.2 WAKEUP function. 7. MEMORY MAP A Harvard architecture, in which the instruction memory space and data memory space are separated is employed. 7.1 Instruction Memory 7.1.1 Instruction memory map The instruction memory space consists of 64K words x 32 bits, and the capacity and type of the memory differ depending on the product.

Although reset is not an interrupt, it is handled like an interrupt as an entry to a vector. 2. It is recommended that unused interrupt source vectors be used to branch an error processing routine. 3. Because a vector area also exists in the internal RAM area of the mask ROM model, this area must be booted up. not used. In addition, because the entry address after reset is 0x200, address 0x200 must be booted up even when the internal instruction RAM and interrupts are 28 Data Sheet U12801EJ4V0DS00 PD77110, 77111, 77112 7.2 Data Memory 7.2.1 Data memory map The data memory space consists of an X memory space and a Y memory space of 64K words x 16 bits each, and the memory capacity and memory type differ depending on the product.

Therefore, when using these names in assembler or C, the user must define them. 2. The same register is accessed, as long as the address is the same, regardless of whether the X memory space or Y memory space is accessed. 3. Even different registers cannot be accessed at the same time from both the X and Y memory spaces. 8. MASK OPTION The PD77111 and 77112 have mask options that must be specified when an order for a ROM is placed. This section explains these mask options. The mask options are specified in the Workbench (WB77016) development tool. To order a mask ROM, output a mask ROM ordering file format (.msk file) using WB77016. 8.1 Clock Control Options The following four clock related options must be specified. * PLL multiple * Output division ratio * HALT division ratio * Validity of CLKOUT pin 30 Data Sheet U12801EJ4V0DS00 PD77110, 77111, 77112 When the PLL multiple is m, output division ratio is n, and halt division ratio is l, the relationship between each operation mode and operating clock is as follows: Operation Mode Normal operation mode HALT mode STOP mode Clock Supplied Inside DSP m/n times external input clock m/n/l times external input clock Stopped The PLL control circuit multiplies the input clock by an integer from 1 to 16. Specify the mask option of the PLL multiple so that the multiplied frequency falls within the specified PLL lock frequency range. The output divider divides the clock multiplied by the PLL by an integer from 1 to 16. Specify the mask option of the output division ratio so that the frequency m/n times the external input clock supplied to the DSP falls within the specified operating frequency range of the DSP. The HALT divider functions only in the HALT mode. It divides the clock of the output divider by an integer from 1 to 16 and supplies the divided clock to the internal circuitry. Specify the mask option of the HALT division ratio so that necessary division can be performed. Whether the clock supplied to the internal circuitry of the DSP (internal system clock) is "output" or "not output" from the CLKOUT pin can be specified. Specify the mask option as necessary. If an odd value (other than 1) is specified as the output division ratio, the high-level width of the clock output from the CLKOUT pin is equal to one cycle during normal operation (i.e., the clock does not have a duty factor of 50%). 8.2 WAKEUP Function The WAKEUP pin can be used to release the STOP mode as well as a hardware reset. If the STOP mode is released by means of a hardware reset, the status before the STOP mode was set cannot be restored after the STOP mode has been released. If the WAKEUP pin is used, however, the status before the STOP mode is set can be retained and program execution can be resumed starting from the instruction after the STOP instruction. Whether the WAKEUP pin is used to release the STOP mode can be specified by a mask option. When the WAKEUP function is specified valid, the WAKEUP pin is multiplexed with the INT4 pin and it usually functions as an interrupt pin. The pin functions as the WAKEUP pin only in the STOP mode (if this pin is asserted active in the STOP mode, it is used only to release the STOP mode, and execution does not branch to an interrupt vector). 8.3 Mask Option Equivalent Function of PD77110 Because the PD77110 does not have mask options, the multiple of the PLL cannot be specified in the same manner as the PD77111 and 77112. However, an external pin on the PD77110 has a function equivalent to the mask option. Care must be exercised when using the PD77110, including when it is used to emulate the PD77111 and 77112. Data Sheet U12801EJ4V0DS00 31 PD77110, 77111, 77112 8.3.1 Settings related to clock control External pins PLL0 through PLL2 are used to set the multiple of the PLL. PLL0 and PLL1 are multiplexed with general-purpose I/O ports P2 and P3, and can be used as PLL setting pins only when it is so specified. The multiple must be an integer from 1 to 8. Operation Mode Normal operation mode HALT mode STOP mode Clock Supplied to DSP m times external input clock m/8 times external input clock Stopped For details on how to set the PLL multiple, refer to 4.2 Initializing PLL. Because the setting of PLL0 through PLL2 becomes valid in the PLL initialization mode, the value of PLL0 through PLL2 must be fixed before the PLL initialization mode is set. The option that makes CLKOUT pin output valid or invalid is fixed to "valid". 8.3.2 WAKEUP function The WAKEUP function of the PD77110 is fixed to "valid". 32 Data Sheet U12801EJ4V0DS00 PD77110, 77111, 77112 9. INSTRUCTIONS 9.1 Outline of Instructions An instruction consists of 32 bits. Almost all the instructions, except some such as branch instructions, are executed with one system clock. The maximum instruction cycle of the PD77110 is 15.3 ns. The maximum instruction cycle of the PD77111 and 77112 is 13.3 ns. The following nine types of instructions are available: (1) Trinomial operation instructions These instructions specify an operation by the MAC. As the operands, three general-purpose registers can be specified. (2) Binomial operation instructions These instructions specify an operation by the MAC, ALU, or BSFT. As the operands, two general-purpose registers can be specified. An immediate value can be specified for some of these instructions, instead of a general-purpose register, for one input. (3) Uninominal operation instructions These instructions specify an operation by the ALU. As the operands, one general-purpose register can be specified. (4) Load/store instructions These instructions transfer 16-bit values between memory and a general-purpose register. Any general-purpose register can be specified as the transfer source or destination. (5) Register-to-register transfer instructions These instructions transfer data from one general-purpose register to another. (6) Immediate value setting instructions These instructions write an immediate value to a general-purpose register and the registers of the address operation unit. (7) Branch instructions These instruction specify branching of program execution. (8) Hardware loop instructions These instruction specify repetitive execution of an instruction. (9) Control instructions These instructions are used to control the program.

Bear in mind the following points when designing your system: * Reinforce the wiring for power supply and ground (if noise is superimposed on the power and ground lines, it has the same effect as if noise were superimposed on the serial clock). * Shorten the wiring between the device's SCK1 and SCK2 pins, and clock supply source. * Do not cross the signal lines of the serial clock with any other signal lines. Do not route the serial clock line in the vicinity of a line through which a high alternating current flows. * Supply the clock to the SCK1 and SCK2 pins of the device from the clock source on a one-toone basis. Do not supply clock to several devices from one clock source. * Exercise care that the serial clock does not overshoot or undershoot. In particular, make sure that the rising and falling of the serial clock waveform are clear. x Make sure that the serial clock rises and falls linearly. The serial clock must not bound. Noise must not be superimposed on the serial clock. x The serial clock must not rise or fall step-wise.

Bear in mind the following points when designing your system: * Reinforce the wiring for power supply and ground (if noise is superimposed on the power and ground lines, it has the same effect as if noise were superimposed on the serial clock). * Shorten the wiring between the device's SCK1 and SCK2 pins, and clock supply source. * Do not cross the signal lines of the serial clock with any other signal lines. Do not route the serial clock line in the vicinity of a line through which a high alternating current flows. * Supply the clock to the SCK1 and SCK2 pins of the device from the clock source on a one-toone basis. Do not supply clock to several devices from one clock source. * Exercise care that the serial clock does not overshoot or undershoot. In particular, make sure that the rising and falling of the serial clock waveform are clear. x Make sure that the serial clock rises and falls linearly. The serial clock must not bound. Noise must not be superimposed on the serial clock. x The serial clock must not rise or fall step-wise. 64 Data Sheet U12801EJ4V0DS00 PD77110, 77111, 77112 PD77111, 77112 Serial output timing 1 tcSC twSC SCK1, SCK2 twSC trfSC trfSC tdSOR thSOR SORQ1 tsuSOE tsuSOE thSOE thSOE SOEN1, SOEN2 tdSO SO1, SO2 Hi-Z 1st tdSO Last thSO Serial output timing 2 (during successive output) tcSC twSC SCK1, SCK2 twSC trfSC trfSC tdSOR thSOR SORQ1 tsuSOE thSOE SOEN1, SOEN2 tdSO SO1, SO2 Last 1st Last thSO Data Sheet U12801EJ4V0DS00 65 PD77110, 77111, 77112 PD77111, 77112 Serial input timing 1 tcSC twSC SCK1, SCK2 twSC trfSC trfSC tdSIA thSIA SIAK1 tsuSIE tsuSIE SIEN1, SIEN2 thSIE thSIE tsuSI SI1, SI2 1st thSI 2nd 3rd Serial input timing 2 (during successive input) tcSC twSC SCK1, SCK2 twSC trfSC trfSC tdSIA thSIA SIAK1 tsuSIE thSIE SIEN1, SIEN2 tsuSI SI1, SI2 thSI Last-1 Last 1st 2nd 3rd 66 Data Sheet U12801EJ4V0DS00 PD77110, 77111, 77112 PD77111, 77112 Host Interface Timing requirements Parameter HRD delay time Symbol tdHR Condition IVDD = 1.8 to 2.7 V IVDD = 2.3 to 2.7 V HRD width HCS, HA0, HA1, read hold time HCS, HA0, HA1 line hold time HRD, HWR recovery time HWR delay time twHR thHCAR MIN. 15 10 60 0 TYP.

Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function. 78 Data Sheet U12801EJ4V0DS00 PD77110, 77111, 77112 Regional Information Some information contained in this document may vary from country to country.
