It combines, on a single chip, the processing power of a DSP and the functionality of a microcontroller with a flexible set of peripherals to create an extremely cost-effective solution. Because of its low cost, configuration flexibility, and compact program code, the 56F8357 is well-suited for many applications. The 56F8357 includes many peripherals that are especially useful for motion control, smart appliances, steppers, encoders, tachometers, limit switches, power supply and control, automotive control, engine management, noise suppression, remote utility metering, industrial control for power, lighting, and automation applications. The 56800E core is based on a Harvard-style architecture consisting of three execution units operating in parallel, allowing as many as six operations per instruction cycle. The MCU-style programming model and optimized instruction set allow straightforward generation of efficient, compact DSP and control code. The instruction set is also highly efficient for C/C++ Compilers to enable rapid development of optimized control applications. The 56F8357 supports program execution from internal or external memories. Two data operands can be accessed from the on-chip data RAM per instruction cycle. The 56F8357 also provides two external dedicated interrupt lines and up to 76 General Purpose Input/Output (GPIO) lines, depending on peripheral configuration. 56F8357 Technical Data Preliminary For More Information On This Product, Go to: www.freescale.com 5 Freescale Semiconductor, Inc. The 56F8357 hybrid controller includes 256KB of Program Flash and 8KB of Data Flash (each programmable through the JTAG port) with 4KB of Program RAM and 16KB of Data RAM. It also supports program execution from external memory. A total of 16KB of Boot Flash is incorporated for easy customer-inclusion of field-programmable software routines that can be used to program the main Program and Data Flash memory areas. Both Program and Data Flash memories can be independently bulk erased or erased in pages. Program Flash page erase size is 1KB. Boot and Data Flash page erase size is 512 bytes. The Boot Flash memory can also be either bulk or page erased. A key application-specific feature of the 56F8357 is the inclusion of two Pulse Width Modulator (PWM) modules. These modules each incorporate three complementary, individually programmable PWM signal output pairs (each module is also capable of supporting six independent PWM functions, for a total of 12 PWM outputs) to enhance motor control functionality. Complementary operation permits programmable dead time insertion, distortion correction via current sensing by software, and separate top and bottom output polarity control. The up-counter value is programmable to support a continuously variable PWM frequency. Edge-aligned and center-aligned synchronous pulse width control (0% to 100% modulation) is supported. The device is capable of controlling most motor types: ACIM (AC Induction Motors); both BDC and BLDC (Brush and Brushless DC motors); SRM and VRM (Switched and Variable Reluctance Motors); and stepper motors. The PWMs incorporate fault protection and cycle-by-cycle current limiting with sufficient output drive capability to directly drive standard optoisolators. A "smoke-inhibit", write-once protection feature for key parameters is also included. A patented PWM waveform distortion correction circuit is also provided. Each PWM is double-buffered and includes interrupt controls to permit integral reload rates to be programmable from 1 to 16. The PWM modules provide a reference output to synchronize the Analog-to-Digital Converters through two channels of Quad Timer C. The 56F8357 incorporates two Quadrature Decoders capable of capturing all four transitions on the two-phase inputs, permitting generation of a number proportional to actual position. Speed computation capabilities accommodate both fast- and slow-moving shafts. An integrated watchdog timer in the Quadrature Decoder can be programmed with a time-out value to alarm when no shaft motion is detected. Each input is filtered to ensure only true transitions are recorded. This hybrid controller also provides a full set of standard programmable peripherals that include two Serial Communications Interfaces (SCIs); two Serial Peripheral Interfaces (SPIs); and four Quad Timers. Any of these interfaces can be used as General Purpose Input/Outputs (GPIOs) if that function is not required. A Flex Controller Area Network (FlexCAN) interface (CAN Version 2.0 B-compliant) and an internal interrupt controller are a part of the 56F8357. Freescale Semiconductor, Inc... 1.3 Award-Winning Development Environment Processor ExpertTM (PE) provides a Rapid Application Design (RAD) tool that combines easy-to-use component-based software application creation with an expert knowledge system. The CodeWarrior Integrated Development Environment is a sophisticated tool for code navigation, compiling, and debugging. A complete set of evaluation modules (EVMs) and development system cards will support concurrent engineering. Together, PE, CodeWarrior and EVMs create a complete, scalable tools solution for easy, fast, and efficient development. 6 For More Information On This Product, Go to: www.freescale.com 56F8357 Technical Data Preliminary Freescale Semiconductor, Inc. Architecture Block Diagram 1.4 Architecture Block Diagram The 56F8357 architecture is shown in Figure 1-1 and Figure 1-2. Figure 1-1 illustrates how the 56800E system buses communicate with internal memories, the external memory interface and the IPBus Bridge. Table 1-1 lists the internal buses in the 56800E architecture and provides a brief description of their function. Figure 1-2 shows the peripherals and control blocks connected to the IPBus Bridge. The figures do not show the on-board regulator and power and ground signals. They also do not show the multiplexing between peripherals or the dedicated GPIOs. Please see Section 2, Signal/Connection Descriptions, to see which signals are multiplexed with those of other peripherals. Also shown in Figure 1-2 are connections between the PWM, Timer C and ADC blocks. These connections allow the PWM and/or Timer C to control the timing of the start of ADC conversions. The Timer C channel indicated can generate periodic start (SYNC) signals to the ADC to start its conversions. In another operating mode, the PWM load interrupt (SYNC output) signal is routed internally to the Timer C input channel as indicated. The timer can then be used to introduce a controllable delay before generating its output signal. The timer output then triggers the ADC. To fully understand this interaction, please see the 56F8300 Peripheral User Manual for clarification on the operation of all three of these peripherals.

Any alternate functionality must be programmed. If the "State During Reset" lists more than one state for a pin, the first state is the actual reset state. Other states show the reset condition of the alternate function, which you get if the alternate pin function is selected without changing the configuration of the alternate peripheral. For example, the A8/GPIOA0 pin shows that it is tri-stated during reset. If the GPIOA_PER is changed to select the GPIO function of the pin, it will become an input if no other registers are changed.

When RESET is asserted low, the device is initialized and placed in the reset state. A Schmitt trigger input is used for noise immunity. When the RESET pin is deasserted, the initial chip operating mode is latched from the EXTBOOT pin. The internal reset signal will be deasserted synchronous with the internal clocks after a fixed number of internal clocks. To ensure complete hardware reset, RESET and TRST should be asserted together. The only exception occurs in a debugging environment when a hardware device reset is required and the JTAG/EOnCE module must not be reset. In this case, assert RESET but do not assert TRST. Note: The internal Power-On Reset will assert on initial power-up. To deactivate the internal pull-up resistor, set the RESET bit in the SIM_PUDR register. See Section 6.5.6 for details. Freescale Semiconductor, Inc... RSTO 97 Output Output Reset Output -- This output reflects the internal reset state of the chip. External Boot -- This input is tied to VDD to force the device to boot from off-chip memory (assuming that the on-chip Flash memory is not in a secure state). Otherwise, it is tied to ground. For details, see Table 4-4. Note: When this pin is tied low, the customer boot software should disable the internal pull-up resistor by setting the XBOOT bit of the SIM_PUDR; see Section 6.5.6. EXTBOOT 124 Schmitt Input Input EMI_MODE 159 Schmitt Input Input External Memory Mode -- This input is tied to VDD in order to enable an extra four address lines, for a total of 20 address lines out of reset. This function is also affected by EXTBOOT and the Flash security mode. For details, see Table 4-4. If a 20-bit address bus is not desired, then this pin is tied to ground. Note: When this pin is tied low, the customer boot software should disable the internal pull-up resistor by setting the EMI_MODE bit of the SIM_PUDR; see Section 6.5.6. 56F8357 Technical Data Preliminary For More Information On This Product, Go to: www.freescale.com 31 Freescale Semiconductor, Inc.

External Clock Operation 3.2 External Clock Operation The 56F8357 system clock can be derived from an external crystal, ceramic resonator, or an external system clock signal. To generate a reference frequency using the internal oscillator, a reference crystal or ceramic resonator must be connected between the EXTAL and XTAL pins. 3.2.1 Crystal Oscillator Freescale Semiconductor, Inc... The internal oscillator is also designed to interface with a parallel-resonant crystal resonator in the frequency range specified for the external crystal in Table 10-13. A recommended crystal oscillator circuit is shown in Figure 3-2. Follow the crystal supplier's recommendations when selecting a crystal, since crystal parameters determine the component values required to provide maximum stability and reliable start-up. The crystal and associated components should be mounted as near as possible to the EXTAL and XTAL pins to minimize output distortion and start-up stabilization time. Crystal Frequency = 4 - 8MHz (optimized for 8MHz) EXTAL XTAL Rz CLKMODE = 0 EXTAL XTAL Rz Sample External Crystal Parameters: Rz = 750 K Note: If the operating temperature range is limited to below 85oC (105oC junction), then Rz = 10 Meg CL1 CL2 Figure 3-2 Connecting to a Crystal Oscillator Note: The OCCS_COHL bit must be set to 1 when a crystal oscillator is used. The reset condition on the OCCS_COHL bit is 0.

A typical ceramic resonator circuit is shown in Figure 3-3. Refer to the supplier's recommendations when selecting a ceramic resonator and associated components. The resonator and components should be mounted as near as possible to the EXTAL and XTAL pins.

The reset condition on the OCCS_COHL bit is 0. Please see the COHL bit in the Oscillator Control (OSCTL) register, discussed in the 56F8300 Peripheral User Manual. 3.2.3 External Clock Source The recommended method of connecting an external clock is given in Figure 3-4. The external clock source is connected to XTAL and the EXTAL pin is grounded. When using an external clock source, set the OCCS_COHL bit high as well. 56F8357 XTAL EXTAL External Clock VSS Note: When using an external clocking source with this configuration, the input "CLKMODE" should be high and the COHL bit in the OSCTL register should be set to 1. Figure 3-4 Connecting an External Clock Signal 3.3 Registers When referring to the register definitions for the OCCS in the 56F8300 Peripheral User Manual, use the register definitions without the internal Relaxation Oscillator, since the 56F8357 does NOT contain this oscillator. 34 For More Information On This Product, Go to: www.freescale.com 56F8357 Technical Data Preliminary Freescale Semiconductor, Inc. Introduction Part 4 Memory Operating Modes (MEM) 4.1 Introduction The 56F8357 device is a 16-bit motor-control chip based on the 56800E core. It uses a Harvard-style architecture with two independent memory spaces for Data and Program. On-chip RAM and Flash memory are used in both spaces. This chapter provides memory maps for: * * Program Address Space including the Interrupt Vector Table Data Address Space including the EOnCE Memory and Peripheral Memory Maps Freescale Semiconductor, Inc... On-chip memory sizes for each device are summarized in Table 4-1. Flash memories' restrictions are identified in the "Use Restrictions" column of Table 4-1.

At reset, these bits are set as indicated in Table 4-2. Table 4-4 shows the memory map configurations that are possible at reset. After reset, the OMR MA bit can be changed and will have an effect on the P-space memory map, as shown in Table 4-3. Changing the OMR MB bit will have no effect Table 4-2 OMR MB/MA Value at Reset OMR MB = Flash Secured State1, 2 OMR MA = EXTBOOT Pin 0 1 0 1 Chip Operating Mode Freescale Semiconductor, Inc... 0 0 1 1 Mode 0 - Internal Boot; EMI is configured to use 16 address lines; Flash Memory is secured; external P-space is not allowed; the EOnCE is disabled Not valid; cannot boot externally if the Flash is secured and will actually configure to 00 state Mode 0 - Internal Boot; EMI is configured to use 16 address lines Mode 1 - External Boot; Flash Memory is not secured; EMI configuration is determined by the state of the EMI_MODE pin 1. This bit is only configured at reset. If the Flash secured state changes, this will not be reflected in MB until the next reset. 2. Changing MB in software will not affect Flash memory security. Table 4-3 Changing OMR MA Value During Normal Operation OMR MA 0 1 Chip Operating Mode Use internal P-space memory map configuration Use external P-space memory map configuration - If MB = 0 at reset, changing this bit has no effect. The 56F8357's external memory interface (EMI) can operate much like the 56F80x family's EMI, or it can be operated in a mode similar to that used on other products in the 56800E family. Initially, CS0 and CS1 are configured as PS and DS, in a mode compatible with earlier 56800 devices. Eighteen address lines are required to shadow the first 192K of internal program space when booting externally for development purposes. Therefore, the entire complement of on-chip memory cannot be accessed using a 16-bit 56800-compatible address bus. To address this situation, the EMI_MODE pin can be used to configure four GPIO pins as Address[19:16] upon reset (Software reconfiguration of the highest address lines [A20-23] is required if the full address range is to be used.) The EMI_MODE pin also affects the reset vector address, as provided in Table 4-4. Additional pins must be configured as address or chip select signals to access addresses at P:$10 0000 and above. 36 For More Information On This Product, Go to: www.freescale.com 56F8357 Technical Data Preliminary Freescale Semiconductor, Inc.

"EMI_MODE = 1" when EMI_MODE pin is tied to VDD at boot up. 5. Not accessible in reset configuration, since the address is above P:$00 FFFF. The higher bit address/GPIO (and/or chip selects) pins must be reconfigured before this external memory is accessible. 6. Not accessible in reset configuration, since the address is above P:$0F FFFF. The higher bit address/GPIO (and/or chip selects) pins must be reconfigured before this external memory is accessible. 7. Booting from this external address allows prototyping of the internal Boot Flash. 8. Two independent program flash blocks allow one to be programmed/erased while executing from another. Each block must have it's own mass erase. 4.3 Interrupt Vector Table Table 4-5 provides the reset and interrupt priority structure, including on-chip peripherals. The table is organized with higher-priority vectors at the top and lower-priority interrupts lower in the table. The priority of an interrupt can be assigned to different levels, as indicated, allowing some control over interrupt priorities. All level 3 interrupts will be serviced before level 2, and so on. For a selected priority level, the lowest vector number has the highest priority. The location of the vector table is determined by the Vector Base Address (VBA) register. Please see Section 5.6.11 for the reset value of the VBA. In some configurations, the reset address and COP reset address will correspond to vector 0 and 1 of the interrupt vector table. In these instances, the first two locations in the vector table must 56F8357 Technical Data Preliminary 37 For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. contain branch or JMP instructions.

The Data RAM is organized as a 2K x 32-bit memory to allow single-cycle, long-word operations. 4.5 Flash Memory Map Figure 4-1 illustrates the Flash Memory (FM) map on the system bus. The Flash Memory is divided into three functional blocks. The Program and boot memories reside on the Program Memory buses. They are controlled by one set of banked registers. Data Memory Flash resides on the Data Memory buses and is controlled separately by its own set of banked registers. The top nine words of the Program Memory Flash are treated as special memory locations. The content of these words is used to control the operation of the Flash Controller. Because these words are part of the Flash Memory content, their state is maintained during power down and reset. During chip initialization, the content of these memory locations is loaded into Flash Memory control registers, detailed in the Flash Memory chapter of the DSP56F8300 Peripheral User Manual. In the 56F8357, these configuration parameters are located between $01_FFF7 and $01_FFFF. 40 For More Information On This Product, Go to: www.freescale.com 56F8357 Technical Data Preliminary Freescale Semiconductor, Inc.

Introduction Part 5 Interrupt Controller (ITCN) 5.1 Introduction The Interrupt Controller (ITCN) module is used to arbitrate between various interrupt requests (IRQs), to signal to the 56800E core when an interrupt of sufficient priority exists, and what address to jump to in order to service this interrupt. 5.2 Features The ITCN module design includes these distinctive features: Freescale Semiconductor, Inc... * * * * Programmable priority levels for each IRQ Two programmable Fast Interrupts Notification to SIM module to restart clocks out of Wait and Stop modes Drives initial address on the address bus after reset 5.3 Functional Description The Interrupt Controller is a slave on the IPBus. It contains registers allowing each of the 82 interrupt sources to be set to one of four priority levels, excluding certain interrupts of fixed priority. Next, all of the interrupt requests of a given level are priority encoded to determine the lowest numerical value of the active interrupt requests for that level. Within a given priority level, 0 is the highest priority, while number 81 is the lowest. 5.3.1 Normal Interrupt Handling Once the ITCN has determined that an interrupt is to be serviced and which interrupt has the highest priority, an interrupt vector address is generated. Normal interrupt handling concatenates the VBA and the vector number to determine the vector address. In this way, an offset is generated into the vector table for each interrupt. 5.3.2 Interrupt Nesting Interrupt exceptions may be nested to allow an IRQ of higher priority than the current exception to be serviced. The following tables define the nesting requirements for each priority level. Table 5-1 Interrupt Mask Bit Definition SR[9]1 0 0 1 1 SR[8]1 0 1 0 1 Permitted Exceptions Priorities 0, 1, 2, 3 Priorities 1, 2, 3 Priorities 2, 3 Priority 3 Masked Exceptions None Priority 0 Priorities 0, 1 Priorities 0, 1, 2 1. Core status register bits indicating current interrupt mask within the core. 56F8357 Technical Data Preliminary For More Information On This Product, Go to: www.freescale.com 69 Freescale Semiconductor, Inc. Table 5-2. Interrupt Priority Encoding IPIC_LEVEL[1:0]1 00 01 01 11 Current Interrupt Priority Level No Interrupt or SWILP Priority 0 Priority 1 Priorities 2 or 3 Required Nested Exception Priority Priorities 0, 1, 2, 3 Priorities 1, 2, 3 Priorities 2, 3 Priority 3 1. See IPIC field definition in Section 5.6.30.2 5.3.3 Fast Interrupt Handling Freescale Semiconductor, Inc... Fast interrupts are described in the DSP56800E Reference Manual. The interrupt controller recognizes fast interrupts before the core does. A fast interrupt is defined (to the ITCN) by: 1. Setting the priority of the interrupt as level 2, with the appropriate field in the IPR registers 2. Setting the FIMn register to the appropriate vector number 3. Setting the FIVALn and FIVAHn registers with the address of the code for the fast interrupt When an interrupt occurs, its vector number is compared with the FIM0 and FIM1 register values. If a match occurs, and it is a level 2 interrupt, the ITCN handles it as a fast interrupt. The ITCN takes the vector address from the appropriate FIVALn and FIVAHn registers, instead of generating an address that is an offset from the VBA. The core then fetches the instruction from the indicated vector adddress and if it is not a JSR, the core starts its fast interrupt handling. 70 For More Information On This Product, Go to: www.freescale.com 56F8357 Technical Data Preliminary Freescale Semiconductor, Inc.

Wait and Stop Modes During Wait and Stop modes, the system clocks and the 56800E core are turned off. The ITCN will signal a pending IRQ to the System Integration Module (SIM) to restart the clocks and service the IRQ. An IRQ can only wake up the core if the IRQ is enabled prior to entering the Wait or Stop mode. Also, the IRQA and IRQB signals automatically become low-level sensitive in these modes even if the control register bits are set to make them falling-edge sensitive. This is because there is no clock available to detect the falling edge. A peripheral which requires a clock to generate interrupts will not be able to generate interrupts during Stop mode. The FlexCAN module can wake the device from Stop mode, and a reset will do just that, or IRQA and IRQB can wake it up. 56F8357 Technical Data Preliminary For More Information On This Product, Go to: www.freescale.com 71 Freescale Semiconductor, Inc. 5.6 Register Descriptions A register address is the sum of a base address and an address offset. The base address is defined at the system level and the address offset is defined at the module level. The ITCN peripheral has 24 registers.

Overview Part 6 System Integration Module (SIM) 6.1 Overview The SIM module is a system catchall for the glue logic that ties together the system-on-chip. It controls distribution of resets and clocks and provides a number of control features. The system integration module is responsible for the following functions: * * * * * * * Reset sequencing Clock generation & distribution Stop/Wait control Pull-up Enables for Selected Peripherals System status registers Registers for software access to the JTAG ID of the chip Enforcing Flash security Freescale Semiconductor, Inc... These are discussed in more detail in the sections that follow. 6.2 Features The SIM has the following features: * * * Flash security feature prevents unauthorized access to code/data contained in on-chip Flash memory Power-saving clock gating for peripheral Three power modes (Run, Wait, Stop) to control power utilization -- Stop mode shuts down 56800E core, system clock, peripheral clock, and PLL operation -- Stop mode entry can optionally disable PLL and Oscillator (low power vs. fast restart); must be explicitly done -- Wait mode shuts down the 56800E core, and unnecessary system clock operation -- Run mode supports full part operation * * * * * * * Controls to enable/disable the 56800E core WAIT and STOP instructions Calculates base delay for reset extension based upon POR or RESET operations. Reset delay will be either 3 x 32 clocks for reset, exept for POR, which is 221 clock cycles Controls reset sequencing after reset Software-initiated reset Four 16-bit registers reset only by a Power-On Reset usable for general-purpose software control System Control Register Registers for software access to the JTAG ID of the chip 56F8357 Technical Data Preliminary For More Information On This Product, Go to: www.freescale.com 97 Freescale Semiconductor, Inc. 6.3 Operating Modes Since the SIM is responsible for distributing clocks and resets across the chip, it must understand the various chip operating modes and take appropriate action. These are: * Reset Mode, which has two submodes: -- POR and RESET operation The 56800E core and all peripherals are reset. This occurs when the internal POR is asserted or the RESET pin is asserted. -- COP reset and software reset operation The 56800E core and all peripherals are reset. The MA bit within the OMR is not changed. This allows the software to determine the boot mode (internal or external boot) to be used on the next reset. Freescale Semiconductor, Inc... * * * * Run Mode This is the primary mode of operation for this device. In this mode, the 56800E controls chip operation Debug Mode The 56800E is controlled via JTAG/EOnCE when in debug mode. All peripherals, except the COP and PWMs, continue to run. COP is disabled and PWM outputs are optionally switched off to disable any motor from being driven; see the PWM chapter in the 56F8300 Peripheral User Manual for details. Wait Mode In Wait mode, the core clock and memory clocks are disabled. Optionally, the COP can be stopped. Similarly, it is an option to switch off PWM outputs to disable any motor from being driven. All other peripherals continue to run. Stop Mode When in Stop mode, the 56800E core, memory, and most peripheral clocks are shut down. Optionally, the COP and CAN can be stopped. For lowest power consumption in Stop mode, the PLL can be shut down. This must be done explicitly before entering Stop mode, since there is no automatic mechanism for this. The CAN (along with any non-gated interrupt) is capable of waking the chip up from Stop mode, but is not fully functional in Stop mode. 6.4 Operation Mode Register Bit Type RESET 15 NL R/W 0 0 0 0 0 0 0 14 13 12 11 10 9 8 CM R/W 0 7 XP R/W 0 6 SD R/W 0 5 R R/W 0 4 SA R/W 0 3 EX R/W 0 2 0 1 MB R/W 0 MA R/W 0 0 0 Figure 6-1 OMR See Section 4.2 for detailed information on how the Operating Mode Register (OMR) MA and MB bits operate in this device.

This bit will be cleared by any hardware reset or by software. Writing a 0 to this bit position will set the bit, while writing a 1 to the bit will clear it. 6.5.2.3 COP Reset (COPR)--Bit 4 When 1, the COPR bit indicates the Computer Operating Properly (COP) timer-generated reset has occurred. This bit will be cleared by a Power-On Reset or by software. Writing a 0 to this bit position will set the bit, while writing a 1 to the bit will clear it. 6.5.2.4 External Reset (EXTR)--Bit 3 If 1, the EXTR bit indicates an external system reset has occurred. This bit will be cleared by a Power-On Reset or by software. Writing a 0 to this bit position will set the bit, while writing a 1 to the bit position will clear it. Basically, when the EXTR bit is 1, the previous system reset was caused by the external RESET pin being asserted low. 56F8357 Technical Data Preliminary For More Information On This Product, Go to: www.freescale.com 101 Freescale Semiconductor, Inc. 6.5.2.5 Power-On Reset (POR)--Bit 2 When 1, the POR bit indicates a Power-On Reset occurred some time in the past.

Pins which can operate as GPIO can have these resistors disabled via the GPIO function. Non-GPIO pins can have their pull-ups disabled by setting the appropriate bit in this register. Disabling pull-ups is done on a peripheral-by-peripheral basis (for pins not muxed with GPIO). Each bit in the register (see Figure 6-8) corresponds to a functional group of pins. See Table 2-2 to identify which pins can deactivate the internal pull-up resistor.

The default value is SYS_CLK. All other clocks primarily muxed out are for test purposes only, and are subject to significant phase shift at high frequencies. The upper four bits of the GPIO B register can function as GPIO, A23 through A20, or as additional clock output signals. GPIO has priority and is enabled/disabled via the GPIOB_PER. If GPIO B[7:4] are programmed to operate as peripheral outputs, then the choice between A23 through A20 and additional clock outputs is done here in the CLKOSR. The default state is for the peripheral function of GPIO B[7:4] to be programmed as A23 through A20. This can be changed by altering A23 through A20 as shown in Figure 6-9.

The default peripheral is Quad Decoder 1 and Quad Timer B; these peripherals work together. The four I/O pins associated with GPIO C can function as GPIO, Quad Decoder 1/Quad Timer B, or as SPI 1 signals. GPIO is not the default and is enabled/disabled via the GPIOC_PER, as shown in Figure 6-10 and Table 6-2. When GPIO C[3:0] are programmed to operate as peripheral I/O, then the choice between decoder/timer and SPI inputs/outputs is made in the SIM_GPS register and in conjunction with the Quad Timer Status and Control Registers (SCR). The default state is for the peripheral function of GPIO C[3:0] to be programmed as decoder functions. This can be changed by altering the appropriate controls in the indicated registers.

The I/O short address mode allows the instruction to specify the lower six bits of address; the upper address bits are not directly controllable. This register set allows limited control of the full address, as shown in Figure 6-13. Note: If this register is set to something other than the top of memory (EOnCE register space) and the EX bit in the OMR is set to 1, the JTAG port cannot access the on-chip EOnCE registers, and debug functions will be affected.

The ISR should restore this register to its previous contents prior to returning from interrupt. Note: Note: The default value of this register set points to the EOnCE registers.

The maximum master clock frequency is 120MHz. Peripheral and system clocks are generated at half the master clock frequency and therefore at a maximum 60MHz. The SIM provides power modes (Stop, Wait) and clock enables (SIM_PCE register, CLK_DIS, ONCE_EBL) to control which clocks are in operation. The OCCS, power modes, and clock enables provide a flexible means to manage power consumption. Power utilization can be minimized in several ways. In the OCCS, crystal oscillator, and PLL may be shut down when not in use. When the PLL is in use, its prescaler and postscaler can be used to limit PLL and master clock frequency. Power modes permit system and/or peripheral clocks to be disabled when unused. Clock enables provide the means to disable individual clocks. Some peripherals provide further controls to disable unused subfunctions. Refer to Part 3, On-Chip Clock Synthesis (OCCS) and the 56F8300 Peripheral User Manual for further details. 56F8357 Technical Data Preliminary For More Information On This Product, Go to: www.freescale.com 111 Freescale Semiconductor, Inc. 6.7 Power Down Modes Overview The 56F8357 operates in one of three power-down modes as shown in Table 6-3. Table 6-3 Clock Operation in Power Down Modes Mode Run Wait Core Clocks Active Core and memory clocks disabled Peripheral Clocks Active Active Description Device is fully functional Peripherals are active and can produce interrupts if they have not been masked off. Interrupts will cause the core to come out of its suspended state and resume normal operation. Typically used for power-conscious applications. The only possible recoveries from Stop mode are: 1. CAN traffic (1st message will be lost) 2. Non-clocked interrupts 3. COP reset 4. External reset 5. Power-on reset Freescale Semiconductor, Inc... Stop System clocks continue to be generated in the SIM, but most are gated prior to reaching memory, core and peripherals. All peripherals, except the COP/watchdog timer, run off the IPBus clock frequency, which is the same as the main processor frequency in this architecture. The maximum frequency of operation is SYS_CLK = 60MHz. 6.8 Stop and Wait Mode Disable Function Permanent Disable D D-FLOP Q C 56800E Reprogrammable Disable D D-FLOP Clock Select Q STOP_DIS C R RESET Note: Wait disable circuit is similar Figure 6-16 Stop Disable Circuit 112 For More Information On This Product, Go to: www.freescale.com 56F8357 Technical Data Preliminary Freescale Semiconductor, Inc. Resets The 56800E core contains both STOP and WAIT instructions. Both put the CPU to sleep. For lowest power consumption in Stop mode, the PLL can be shut down. This must be done explicitly before entering Stop mode, since there is no automatic mechanism for this. When the PLL is shut down, the 56800E system clock must be set equal to the oscillator output. Some applications require the 56800E STOP and WAIT instructions be disabled. To disable those instructions, write to the SIM control register (SIM_CONTROL), described in Section 6.5.1. This procedure can be on either a permanent or temporary basis. Permanently assigned applications last only until their next reset. 6.9 Resets Freescale Semiconductor, Inc... The SIM supports four sources of reset. The two asynchronous sources are the external RESET pin and the Power-On Reset (POR). The two synchronous sources are the software reset, which is generated within the SIM itself by writing to the SIM_CONTROL register and the COP reset. Reset begins with the assertion of any of the reset sources. Release of reset to various blocks is sequenced to permit proper operation of the device. A POR reset is first extended for 221 clock cycles to permit stabilization of the clock source, followed by a 32 clock window in which SIM clocking is initiated. It is then followed by a 32 clock window in which peripherals are released to implement Flash security, and, finally, followed by a 32 clock window in which the core is initialized. After completion of the described reset sequence, application code will begin execution. Resets may be asserted asynchronously, but are always released internally on a rising edge of the system clock. 56F8357 Technical Data Preliminary For More Information On This Product, Go to: www.freescale.com 113 Freescale Semiconductor, Inc. Part 7 Security Features The 56F8357 offers security features intended to prevent unauthorized users from reading the contents of the Flash memory (FM) array. The 56F8357's Flash security consists of several hardware interlocks that block the means by which an unauthorized user could gain access to the Flash array. However, part of the security must lie with the user's code. An extreme example would be user's code that dumps the contents of the internal program, as this code would defeat the purpose of security. At the same time, the user may also wish to put a "backdoor" in his program. As an example, the user downloads a security key through the SCI, allowing access to a programming routine that updates parameters stored in another section of the Flash. Freescale Semiconductor, Inc... 7.1 Operation with Security Enabled Once the user has programmed the Flash with his application code, the 56F8357 can be secured by programming the security bytes located in the FM configuration field, which occupies a portion of the FM array. These non-volatile bytes will keep the part secured through reset and through power-down of the device. Only two bytes within this field are used to enable or disable security. Refer to the Flash Memory section in the 56F8300 Peripheral User Manual for the state of the security bytes and the resulting state of security. When Flash security mode is enabled in accordance with the method described in the Flash Memory module specification, the 56F8357 will disable external P-space accesses restricting code execution to internal memory, disable EXTBOOT=1 mode, and disable the core EOnCE debug capabilities. Normal program execution is otherwise unaffected. 7.2 Flash Access Blocking Mechanisms The 56F8357 has several operating functional and test modes. Effective Flash security must address operating mode selection and anticipate modes in which the on-chip Flash can be compromised and read without explicit user permission. Methods to block these are outlined in the next subsections. 7.2.1 * * * Forced Operating Mode Selection Internal Boot Mode External Boot Mode Secure Mode At boot time, the SIM determines in which functional modes the 56F8357 will operate. These are: When Flash security is enabled as described in the Flash Memory module specification, the 56F8357 will boot in internal boot mode, disable all access to external P-space, and start executing code from the Boot Flash at address 0x02_0000. This security affords protection only to applications in which the 56F8357 operates in internal Flash security mode. Therefore, the security feature cannot be used unless all executing code resides on-chip. When security is enabled, any attempt to override the default internal operating mode by asserting the EXTBOOT pin in conjunction with reset will be ignored. 114 For More Information On This Product, Go to: www.freescale.com 56F8357 Technical Data Preliminary Freescale Semiconductor, Inc. Flash Access Blocking Mechanisms 7.2.2 Disabling EOnCE Access On-chip Flash can be read by issuing commands across the EOnCE port, which is the debug interface for the 56800E core. The TRST, TCLK, TMS, TDO, and TDI pins comprise a JTAG interface onto which the EOnCE port functionality is mapped. When the 56F8357 boots, the chip-level JTAG TAP (Test Access Port) is active and provides the chip's boundary scan capability and access to the ID register. Proper implementation of Flash security requires that no access to the EOnCE port is provided when security is enabled. The 56800E core has an input which disables reading of internal memory via the JTAG/EOnCE. The FM sets this input at reset to a value determined by the contents of the FM security bytes. Freescale Semiconductor, Inc... 7.2.3 Flash LOCKOUT_RECOVERY If a user inadvertently enables security on the 56F8357, a lockout recovery mechanism is provided which allows the complete erasure of the internal Flash contents, including the configuration field, and thus disables security (the protection register is ignored). This does not compromise security, as the entire contents of the user's secured code stored in Flash are erased before security is disabled on the 56F8357 on the next reset or power-up sequence. To start the lockout recovery sequence, the JTAG public instruction (LOCKOUT_RECOVERY) must first be shifted into the chip-level TAP controller's instruction register. The LOCKOUT_RECOVERY instruction will have an associated 7-bit Data Register (DR) that is used to control the clock divider circuit within the FM module. This divider, FM_CLKDIV[6:0], is used to control the period of the clock used for timed events in the FM erase algorithm. This register must be set with appropriate values before the lockout sequence can begin. Refer to the JTAG section of the 56F8300 Peripheral User Manual for more details on setting this register value. The value of the JTAG FM_CLKDIV[6:0] will replace the value of the FM register FMCLKD that divides down the system clock for timed events, as illustrated in Figure 7-1. FM_CLKDIV[6] will map to the PRDIV8 bit, and FM_CLKDIV[5:0] will map to the DIV[5:0] bits. The combination of PRDIV8 and DIV must divide the FM input clock down to a frequency of 150kHz-200kHz. The "Writing the FMCLKD Register" section in the Flash Memory chapter of the 56F8300 Peripheral User Manual gives specific equations for calculating the correct values. 56F8357 Technical Data Preliminary For More Information On This Product, Go to: www.freescale.com 115 Freescale Semiconductor, Inc. Flash Memory SYS_CLK 2 input clock 7 FMCLKD 7 7 DIVIDER FM_CLKDIV JTAG FM_ERASE Freescale Semiconductor, Inc... Figure 7-1 JTAG to FM Connection for LOCKOUT_RECOVERY Two examples of FM_CLKDIV calculations follow. EXAMPLE 1: If the system clock is the 8MHz crystal frequency because the PLL has not been set up, the input clock will be below 12.8MHz, so PRDIV8 = FM_CLKDIV[6] = 0. Using the following equation yields a DIV value of 19 for a clock of 200kHz, and a DIV value of 20 for a clock of 190kHz. This translates into an FM_CLKDIV[6:0] value of $13 or $14, respectively. 150[kHz] ( < SYS_CLK (2) (DIV + 1) )< 200[kHz] EXAMPLE 2: In this example, the system clock has been set up with a value of 32MHz, making the FM input clock 16MHz. Because that is greater than 12.8MHz, PRDIV8 = FM_CLKDIV[6] = 1. Using the following equation yields a DIV value of 9 for a clock of 200kHz, and a DIV value of 10 for a clock of 181kHz. This translates to an FM_CLKDIV[6:0] value of $49 or $4A, respectively. 150[kHz] ( < SYS_CLK (2)(8) (DIV + 1) )< 200[kHz] Once the LOCKOUT_RECOVERY instruction has been shifted into the instruction register, the clock divider value must be shifted into the corresponding 7-bit data register. After the data register has been updated, the user must transition the TAP controller into the RUN-TEST/IDLE state for the lockout sequence to commence. The controller must remain in this state until the erase sequence has completed. For details, see the JTAG Section in the 56F8300 Peripheral User Manual. 116 For More Information On This Product, Go to: www.freescale.com 56F8357 Technical Data Preliminary Freescale Semiconductor, Inc. Flash Access Blocking Mechanisms Note: Once the lockout recovery sequence has completed, the user must reset both the JTAG TAP controller (by asserting TRST) and the 56F8357 (by asserting external chip reset) to return to normal unsecured operation. 7.2.4 Product Analysis The recommended method of unsecuring a programmed 56F8357 for product analysis of field failures is via the backdoor key access. The customer would need to supply Motorola with the backdoor key and the protocol to access the backdoor routine in the Flash. Additionally, the KEYEN bit that allows backdoor key access must be set. An alternative method for performing analysis on a secured microcontroller would be to mass-erase and reprogram the Flash with the original code, but modify the security bytes. Freescale Semiconductor, Inc... To insure that a customer does not inadvertently lock himself out of the 56F8357 during programming, it is recommended that he program the backdoor access key first, his application code second, and the security bytes within the FM configuration field last. 56F8357 Technical Data Preliminary For More Information On This Product, Go to: www.freescale.com 117 Freescale Semiconductor, Inc.

Part 9 Joint Test Action Group (JTAG) 9.1 56F8357 Information Please contact your Motorola marketing representative for device/package-specific BSDL information. Freescale Semiconductor, Inc... Part 10 Specifications 10.1 General Characteristics The 56F8357 is fabricated in high-density CMOS with 5V-tolerant TTL-compatible digital inputs. The term "5V-tolerant" refers to the capability of an I/O pin, built on a 3.3V-compatible process technology, to withstand a voltage up to 5.5V without damaging the device. Many systems have a mixture of devices designed for 3.3V and 5V power supplies. In such sytems, a bus may carry both 3.3V- and 5V-compatible I/O voltage levels (a standard 3.3V I/O is designed to receive a maximum voltage of 3.3V 10% during normal operation without causing damage). This 5V-tolerant capability therefore offers the power savings of 3.3V I/O levels combined with the ability to receive 5V levels without damage. Absolute maximum ratings in Table 10-1 are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond these ratings may affect device reliability or cause permanent damage to the device. Note: All specifications meet both Automotive and Industrial requirements unless individual specifications are listed. CAUTION This device contains protective circuitry to guard against damage due to high static voltage or electrical fields. However, normal precautions are advised to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level. 122 For More Information On This Product, Go to: www.freescale.com 56F8357 Technical Data Preliminary Freescale Semiconductor, Inc.

Theta-JA determined on 2s2p test boards is frequently lower than would be observed in an application. Determined on 2s2p thermal test board. 2. Junction to ambient thermal resistance, Theta-JA (RJA) was simulated to be equivalent to the JEDEC specification JESD51-2 in a horizontal configuration in natural convection. Theta-JA was also simulated on a thermal test board with two internal planes (2s2p where "s" is the number of signal layers and "p" is the number of planes) per JESD51-6 and JESD51-7. The correct name for Theta-JA for forced convection or with the non-single layer boards is Theta-JMA. 3. Junction to case thermal resistance, Theta-JC (RJC ), was simulated to be equivalent to the measured values using the cold plate technique with the cold plate temperature used as the "case" temperature. The basic cold plate measurement technique is described by MIL-STD 883D, Method 1012.1. This is the correct thermal metric to use to calculate thermal performance when the package is being used with a heat sink. 4. Thermal Characterization Parameter, Psi-JT (JT ), is the "resistance" from junction to reference point thermocouple on top center of case as defined in JESD51-2. JT is a useful value to use to estimate junction temperature in steady state customer environments. 5. Junction temperature is a function of on-chip power dissipation, package thermal resistance, mounting site (board) temperature, ambient temperature, air flow, power dissipaion of other components on the board, and board thermal resistance. 6.

Figure 10-4 shows sample timing and parameters that are detailed in Table 10-16. The timing of each parameter consists of both a fixed delay portion and a clock related portion, as well as user controlled wait states. The equation: t = D + P * (M + W) should be used to determine the actual time of each parameter. The terms in this equation are defined as: t D P M W = Parameter delay time = Fixed portion of the delay, due to on-chip path delays = Period of the system clock, which determines the execution rate of the part (i.e., when the device is operating at 60MHz, P = 16.67 ns) = Fixed portion of a clock period inherent in the design; this number is adjusted to account for possible derating of clock duty cycle = Sum of the applicable wait state controls. The "Wait State Controls" column of Table 10-16 shows the applicable controls for each parameter and the EMI chapter of the 56F8300 Peripheral User Manual details what each wait state field controls. When using the XTAL clock input directly as the chip clock without prescaling (ZSRC selects prescaler clock and prescaler set to / 1), the EMI quadrature clock is generated using both edges of the EXTAL clock input. In this one situation parameter values need to be adjusted for the duty cycle at XTAL. DCAOE and DCAEO are used to make this duty cycle adjustment where needed. 132 For More Information On This Product, Go to: www.freescale.com 56F8357 Technical Data Preliminary Freescale Semiconductor, Inc. External Memory Interface Timing DCAOE and DCAEO are calculated as follows: DCAOE = 0.5 - MAX XTAL duty cycle, if ZSRC selects prescaler clock and the prescaler is set to / 1 = 0.0 all other cases DCAEO = MIN XTAL duty cycle - 0.5, if ZSRC selects prescaler clock and the prescaler is set to / 1 = 0.0 all other cases Example of DCAOE and DCAEO calculation: Assuming prescaler is set for / 1 and prescaler clock is selected by ZSRC, if XTAL duty cycle ranges between 45% and 60% high; DCAOE = .50 - .60 = - 0.1 DCAEO = .45 - .50 = - 0.05 Freescale Semiconductor, Inc... The timing of write cycles is different when WWS = 0 than when WWS > 0. Therefore, some parameters contain two sets of numbers to account for this difference. Use the "Wait States Configuration" column of Table 10-16 to make the appropriate selection.

The data was taken on 14 parts: three each from three processing corner lots and two from the fourth processing corner lot, as well as three from one nominally processed lot, each at three temperatures: -40C, 27C, and 150C (giving the 42 data points shown above), for two input DC voltages: 0.60V and 2.70V. The data indicates that for the given population of parts, calibration significantly reduced (by as much as 28%) the collective variation (spread) of the absolute error of the population. It also significantly reduced (by as much as 80%) the mean (average) of the 146 56F8357 Technical Data Preliminary For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc.

When the switches are flipped, the charge on C1 and C2 are averaged via S3, with the result that a single-ended analog input is switched to a differential voltage centered about VREFH - VREFH / 2. The switches switch on every cycle of the ADC clock (open one-half ADC clock, closed one-half ADC clock). Note that there are additional capacitances associated with the analog input pad, routing, etc., but these do not filter into the S/H output voltage, as S1 provides isolation during the charge-sharing phase. One aspect of this circuit is that there is an on-going input current, which is a function of the analog input voltage, VREF and the ADC clock frequency.

Power consumption is given by the following equation: Total power = + + + + A: internal [static component] B: internal [state-dependent component] C: internal [dynamic component] D: external [dynamic component] E: external [static] A, the internal [static component], is comprised of the DC bias currents for the oscillator, leakage current, PLL, and voltage references. These sources operate independently of processor state or operating frequency. 56F8357 Technical Data Preliminary For More Information On This Product, Go to: www.freescale.com 147 Freescale Semiconductor, Inc. B, the internal [state-dependent component], reflects the supply current required by certain on-chip resources only when those resources are in use. These include RAM, Flash memory and the ADCs. C, the internal [dynamic component], is classic C*V2*F CMOS power dissipation corresponding to the 56800E core and standard cell logic. D, the external [dynamic component], reflects power dissipated on-chip as a result of capacitive loading on the external pins of the chip. This is also commonly described as C*V2*F, although simulations on two of the IO cell types used on the 56F8357 reveal that the power-versus-load curve does have a non-zero Y-intercept. Freescale Semiconductor, Inc... Table 10-25 IO Loading Coefficients at 10MHz Intercept PDU08DGZ_ME PDU04DGZ_ME 1.3 1.15mW Slope 0.11mW / pF 0.11mW / pF Power due to capacitive loading on output pins is (first order) a function of the capacitive load and frequency at which the outputs change. Table 10-25 provides coefficients for calculating power dissipated in the IO cells as a function of capacitive load. In these cases: TotalPower = ((Intercept +Slope*Cload)*frequency/10MHz) where: * * * Summation is performed over all output pins with capacitive loads TotalPower is expressed in mW Cload is expressed in pF Because of the low duty cycle on most device pins, power dissipation due to capacitive loads was found to be fairly low when averaged over a period of time. The one possible exception to this is if the chip is using the external address and data buses at a rate approaching the maximum system rate. In this case, power from these buses can be significant. E, the external [static component], reflects the effects of placing resistive loads on the outputs of the device. Sum the total of all V2/R or IV to arrive at the resistive load contribution to power. Assume V = 0.5 for the purposes of these rough calculations. For instance, if there is a total of 8 PWM outputs driving 10mA into LEDs, then P = 8*.5*.01 = 40mW. In previous discussions, power consumption due to parasitics associated with pure input pins is ignored, as it is assumed to be negligible. 148 For More Information On This Product, Go to: www.freescale.com 56F8357 Technical Data Preliminary Freescale Semiconductor, Inc.

Thermal Design Considerations Part 12 Design Considerations 12.1 Thermal Design Considerations An estimation of the chip junction temperature, TJ, can be obtained from the equation: TJ = TA + (RJ x PD) where: TA = Ambient temperature for the package (oC) RJ = Junction-to-ambient thermal resistance (oC/W) PD = Power dissipation in the package (W) Freescale Semiconductor, Inc... The junction-to-ambient thermal resistance is an industry-standard value that provides a quick and easy estimation of thermal performance. Unfortunately, there are two values in common usage: the value determined on a single-layer board and the value obtained on a board with two planes. For packages such as the PBGA, these values can be different by a factor of two. Which value is closer to the application depends on the power dissipated by other components on the board. The value obtained on a single-layer board is appropriate for the tightly packed printed circuit board. The value obtained on the board with the internal planes is usually appropriate if the board has low-power dissipation and the components are well separated. When a heat sink is used, the thermal resistance is expressed as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance: RJ = RJ + RC where: RJA RJC RCA = Package junction-to-ambient thermal resistance C/W = Package junction-to-case thermal resistance C/W = Package case-to-ambient thermal resistance C/W R JC is device-related and cannot be influenced by the user. The user controls the thermal environment to change the case-to-ambient thermal resistance, R CA . For instance, the user can change the size of the heat sink, the air flow around the device, the interface material, the mounting arrangement on printed circuit board, or change the thermal dissipation on the printed circuit board surrounding the device. To determine the junction temperature of the device in the application when heat sinks are not used, the Thermal Characterization Parameter (JT) can be used to determine the junction temperature with a measurement of the temperature at the top center of the package case using the following equation: TJ = TT + (JT x PD) where: TT = Thermocouple temperature on top of package (oC) JT = Thermal characterization parameter (oC)/W PD = Power dissipation in package (W) 56F8357 Technical Data Preliminary For More Information On This Product, Go to: www.freescale.com 153 Freescale Semiconductor, Inc. The thermal characterization parameter is measured per JESD51-2 specification using a 40-gauge type T thermocouple epoxied to the top center of the package case. The thermocouple should be positioned so that the thermocouple junction rests on the package. A small amount of epoxy is placed over the thermocouple junction and over about 1mm of wire extending from the junction. The thermocouple wire is placed flat against the package case to avoid measurement errors caused by cooling effects of the thermocouple wire. When heat sink is used, the junction temperature is determined from a thermocouple inserted at the interface between the case of the package and the interface material. A clearance slot or hole is normally required in the heat sink. Minimizing the size of the clearance is important to minimize the change in thermal performance caused by removing part of the thermal interface to the heat sink. Because of the experimental difficulties with this technique, many engineers measure the heat sink temperature and then back-calculate the case temperature using a separate measurement of the thermal resistance of the interface. From this case temperature, the junction temperature is determined from the junction-to-case thermal resistance. Freescale Semiconductor, Inc... 12.2 Electrical Design Considerations CAUTION This device contains protective circuitry to guard against damage due to high static voltage or electrical fields. However, normal precautions are advised to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level. Use the following list of considerations to assure correct operation: * * Provide a low-impedance path from the board power supply to each VDD pin on the hybrid controller, and from the board ground to each VSS (GND) pin The minimum bypass requirement is to place six 0.01-0.1F capacitors positioned as close as possible to the package supply pins. The recommended bypass configuration is to place one bypass capacitor on each of the VDD/VSS pairs, including VDDA/VSSA. Ceramic and tantalum capacitors tend to provide better performance tolerances. Ensure that capacitor leads and associated printed circuit traces that connect to the chip VDD and VSS (GND) pins are less than 0.5 inch per capacitor lead Use at least a four-layer Printed Circuit Board (PCB) with two inner layers for VDD and VSS Bypass the VDD and VSS layers of the PCB with approximately 100F, preferably with a high-grade capacitor such as a tantalum capacitor Because the 56F8357's output signals have fast rise and fall times, PCB trace lengths should be minimal Consider all device loads as well as parasitic capacitance due to PCB traces when calculating capacitance. This is especially critical in systems with higher capacitive loads that could create higher transient currents in the VDD and VSS circuits. 56F8357 Technical Data Preliminary * * * * * 154 For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. Power Distribution and I/O Ring Implementation * * Take special care to minimize noise levels on the VREF, VDDA and VSSA pins Designs that utilize the TRST pin for JTAG port or EOnCE module functionality (such as development or debugging systems) should allow a means to assert TRST whenever RESET is asserted, as well as a means to assert TRST independently of RESET. Designs that do not require debugging functionality, such as consumer products, should tie these pins together. Because the Flash memory is programmed through the JTAG/EOnCE port, the designer should provide an interface to this port to allow in-circuit Flash programming * 12.3 Power Distribution and I/O Ring Implementation Figure 12-1 illustrates the general power control incorporated in the 56F8357.
