1.2 56F8013/56F8011 Description
The 56F8013/56F8011 is a member of the 56800E core-based family of Digital Signal Controllers (DSCs). 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 56F8013/56F8011 is well-suited for many applications. The 56F8013/56F8011 includes many peripherals that are especially useful for industrial control, motion control, home appliances, general purpose inverters, smart sensors, fire and security systems, switched mode power supply, power management, and medical monitoring applications. The 56800E core is based on a dual 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 compilers to enable rapid development of optimized control applications. The 56F8013/56F8011 supports program execution from internal memories. Two data operands can be accessed from the on-chip data RAM per instruction cycle. The 56F8013/56F8011 also offers up to 26 General Purpose Input/Output (GPIO) lines, depending on peripheral configuration. The 56F8013 Digital Signal Controller includes 16KB of Program Flash and 4KB of Unified Data/Program RAM. The 56F8011 Digital Signal Controller includes 12KB of Program Flash and 2KB of Unified Data/Program RAM. Program Flash memory can be independently bulk erased or erased in pages. Program Flash page erase size is 512 Bytes (256 Words). A full set of programmable peripherals--PWM, ADCs, SCI, SPI, I2C, Quad Timer--supports various applications. Each peripheral can be independently shut down to save power. Any pin in these peripherals can also be used as General Purpose Input/Outputs (GPIOs).

Award-Winning Development Environment
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), demonstration board kit 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.
1.4 Architecture Block Diagram
The 56F8013/56F8011's architecture is shown in Figure 1-1, Figure 1-2, and Figure 1-3. Figure 1-1 illustrates how the 56800E system buses communicate with internal memories and the IPBus Bridge and the internal connections between each unit of the 56800E core. Figure 1-2 shows the peripherals and control blocks connected to the IPBus Bridge. Figure 1-3 details how the device's I/O pins are muxed. The figures do not show the on-board regulator and power and ground signals. Please see Part 2, Signal/Connection Descriptions, to see which signals are multiplexed with those of other peripherals.
1.5 Synchronize ADC with PWM
ADC conversion can be synchronized with PWM module via Quad Timer channel 2 and 3 if needed. Internally, the PWM synch signal, which is generated at every PWM reload, can be connected to the timer channel 3 input and the timer channel 2 and 3 outputs are connected to ADC sync inputs. Timer channel 3 output is connected to SYNC0 and Timer channel 2 is connected to SYNC1. The setting is controlled by TC3_INP bit in the SIM Control Register; see Section 6.3.1. SYNC0 is the master ADC sync input is used to trigger both ADCA and ADCB in sequence and parallel mode. SYNC1 is used to trigger ADCB in parallel independent mode, while SYNC0 is used to trigger ADCA. See 56F801X Peripheral Reference Manual for additional information.
1.6 Multiple Frequency PWM
When both PWM channels of a complementary pair in software control mode and software control bits are set to 1, each complementary PWM signal pair--PWM 0 and 1; PWM 2 and 3; PWM 4 and 5--can select a PWM source of one of following sources that enables each PWM pair to output different frequency PWM signal. * External GPIO input: -- GPIOB2 input can be used to drive PWM 0 and 1 -- GPIOB3 input can be used to drive PWM 2 and 3 -- GPIOB4 input can be used to drive PWM 4 and 5 Quad Timer output: -- Timer0 output can be used to drive PWM 0 and 1

Part 3 OCCS
3.1 Overview
This module provides the system clock, which is used to generate the various chip clocks. This module also produces the oscillator clock plus the ADC clock and high-speed peripheral clock. The on-chip clock synthesis module allows product design using an internal relaxation oscillator to run 56F801X family parts at user-selectable frequencies up to 32MHz.
3.2 Features
The On-Chip Clock Synthesis (OCCS) module interfaces to the oscillator and PLL. The OCCS module features:
* * * * * * * * * Internal relaxation oscillator Ability to power down the internal relaxation oscillator Ability to put the internal relaxation oscillator into a standby mode 3-bit postscaler provides control for the PLL output Ability to power down the internal PLL Provides 2X system clock, which operates at twice the system clock, to the System Integration Model (SIM) that is used to generate the various device clocks Provides 3X system clock, which operates at three times the system clock, to PWM and Timer Safety shutdown feature is available in the event that the PLL reference clock is lost Can be driven from an external clock source
The clock generation module provides the programming interface for both the PLL and internal relaxation oscillator.
3.3 Operating Modes
In 56F801X family parts, either an internal oscillator or an external frequency source can be used to provide a reference clock to the SIM. The 2X system clock source output from the OCCS can be described by one of the following equations: 2X system frequency = oscillator frequency 2X system frequency = (oscillator frequency X 8) / (postscaler) where: postscaler = 1, 2, 4, 8, 16, or 32 PLL output divider The SIM is responsible for further dividing these frequencies by two, which will insure a 50% duty cycle in the system clock output.
56F8013/56F8011 Data Sheet, Rev. 12 26 Freescale Semiconductor
Operating Modes
The 56F801X family parts' on-chip clock synthesis module has the following registers:
* * * * * Control Register (OCCS_CR) Divide-by Register (OCCS_DB) Status Register (OCCS_SR) Shutdown Register (OCCS_SHUTDN) Oscillator Control Register (OCCS_OCTRL)
For more information on these registers, please refer to the 56F801X Peripheral Reference Manual.

Part 4 Memory Map
4.1 Introduction
The 56F8013/56F8011 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 is used in both spaces and Flash memory is used only in Program space. This section provides memory maps for:
* * Program Address Space, including the Interrupt Vector Table Data Address Space, including the EOnCE Memory and Peripheral Memory Maps
On-chip memory sizes for the device are summarized in Table 4-1. Flash memories' restrictions are identified in the "Use Restrictions" column of Table 4-1. Table 4-1 Chip Memory Configurations

4.2 Interrupt Vector Table
Table 4-2 provides the 56F8013/56F8011's 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. As indicated, the priority of an interrupt can be assigned to different levels, 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). Please see Section 5.5.6 for the reset value of the VBA. By default, VBA = 0, and 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 contain branch or JMP instructions. All other entries must contain JSR instructions.

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 to what address to jump in order to service this interrupt.
5.2 Features
The ITCN module design includes these distinctive features:
* * * * Programmable priority levels for each IRQ Two programmable Fast Interrupts Notification to SIM module to restart clocks out of Wait and Stop modes Ability to drive initial address on the address bus after reset
For further information, see Table 4-2, Interrupt Vector Table Contents.
5.3 Functional Description
The Interrupt Controller contains registers that allow each of the 46 interrupt sources to be set to one of four priority levels (excluding certain interrupts that are of fixed priority). 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, number 0 is the highest priority and number 45 is the lowest. During Wait and Stop modes, the system clocks and the 56800E core are turned off. The ITCN can wake up the core and restart system clocks by signaling 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.

5.3.1
Normal Interrupt Handling
Once the INTC 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 Vector Base Address (VBA) and the vector number to determine the vector address, generating an offset 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 table defines the nesting requirements for each priority level.
Table 5-1 Interrupt Mask Bit Definition
SR[9]
0 0 1 1
SR[8]
0 1 0 1
Exceptions Permitted Priorities 0, 1, 2, 3 Priorities 1, 2, 3 Priorities 2, 3 Priority 3
Exceptions Masked None Priority 0 Priorities 0, 1 Priorities 0, 1, 2
5.3.3
Fast Interrupt Handling
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.

5.5 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 module has 16 registers.

These values determine which IRQ will be Fast Interrupt 0. Fast Interrupts vector directly to a service routine based on values in the Fast Interrupt Vector Address registers without having to go to a jump table first. IRQs used as Fast Interrupts must be set to priority level 2. Unexpected results will occur if a Fast Interrupt vector is set to any other priority. A Fast Interrupt automatically becomes the highest-priority level 2 interrupt regardless of its location in the interrupt table prior to being declared as Fast Interrupt. Fast Interrupt 0 has priority over Fast Interrupt 1. To determine the vector number of each IRQ, refer to the vector table.

SIM Reset Status Register (SIM_RSTAT)
This register is updated upon any system reset and indicates the cause of the most recent reset. It also controls whether the COP reset vector or regular reset vector in the vector table is used. This register is asynchronously reset during Power-On Reset (see power supervisor module) and subsequently is synchronously updated based on the level of the external reset, software reset, or cop reset inputs. Only one source will ever be indicated. In the event that multiple reset sources assert simultaneously, the highest-precedence source will be indicated. The precedence from highest to lowest is POR, EXTR, COPR, and SWR. While POR is always set during a Power-On Reset, EXTR will become set if the external reset pin is asserted or remains asserted after the Power-On Reset (POR) has deasserted.

generation and SIM modules. All functionality is for test purposes only and is subject to unspecified latencies. Glitches may be produced when the clock is enabled or switched.
The lower four bits of the GPIO A register can function as GPIO, PWM, or as additional clock output signals. GPIO has priority and is enabled/disabled via the GPIOA_PEREN. If GPIOA[3:0] are programmed to operate as peripheral outputs, then the choice between PWM and additional clock outputs is done here in the CLKOUT. The default state is for the peripheral function of GPIOA[3:0] to be programmed as PWM. This can be changed by altering PWM3 through PWM0.

SIM GPIO Peripheral Select Register (SIM_GPS)
All of the peripheral pins on the 56F8013/56F8011 share their Input/Output (I/O) with GPIO ports. To select peripheral or GPIO control, program corresponding bit in the GPIOx_PEREN register in GPIO module. See the 56F801x Peripheral Reference Manual for detail. In some cases, there are two possible peripherals as well as the GPIO functionality available for control of the I/O. In these cases, the SIM_GPS register is used to determine which peripheral has control when the corresponding I/O pin is configured in peripheral mode. As shown in Figure 6-9, the GPIO Peripheral Enable Register (PEREN) has the final control over which pin controls the I/O. SIM_GPS simply decides which peripheral will be routed to the I/O when PEREN = 1.

NOTE:
Take care when programming the following CFG_* signals so as not to connect two different I/O pins to the same peripheral input. For example, do not set CFG_B7 to select SCL and also set CFG_B0 to select SCL. If this occurs for an output signal, then the signal will be routed to two I/O pins. For input signals, the values on the two I/O pins will be ORed together before reaching the peripheral.

Peripheral Clock Enable Register (SIM_PCE)
The Peripheral Clock Enable register is used to enable or disable clocks to the peripherals as a power savings feature. The clocks can be individually controlled for each peripheral on the chip. The corresponding peripheral should itself be disabled while its clock is shut off.

I/O Short Address Location Register (SIM_IOSAHI and SIM_IOSALO)
The I/O Short Address Location registers are used to specify the memory referenced via the I/O short address mode. 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 6-12.

6.4 Clock Generation Overview
The SIM uses master clocks, 2X system clock at a maximum of 64MHz, from the OCCS module to produce the peripheral and system (core and memory) clocks at a maximum of 32MHz. It divides the master clock by two and gates it with appropriate power mode and clock gating controls. The high speed peripheral clock from OCCS operates at three times the system clock for PWM and Quad Timer module at a maximum of 96MHz. The OCCS configuration controls the operating frequency of the SIM's master clocks. In the OCCS, either an external clock or the relaxation oscillator can be selected as the master clock source (MSTR_OSC). The relaxation oscillator can be operated at full speed (8MHz), standby speed (200kHz), or powered down. An 8MHz clock can be multiplied to 192 MHz using the PLL and postscaled to provide a variety of high speed clock rates. Either the postscaled PLL output or input clock of PLL signal can be selected to produce the master clocks to the SIM. When the PLL is not selected, the high speed peripheral clock is disabled and the 2X system clock is input clock from either internal relaxation oscillator or external clock source. In combination with the OCCS module, the SIM provides power modes (see Section 6.5), clock enables (SIM_PCE register, CLK_DIS, ONCE_EBL), and clock rate controls (TCR, PCR) to provide flexible control of clocking and power utilization. The SIM's clock enable controls can be used to disable individual clocks when not needed. The clock rate controls enable the high speed clocking option for the Timer channels and PWM but require the PLL to be on and selected. Refer to the 56F801X Peripheral User Manual for further details.
6.5 Power-Down Modes
The 56F8013/56F8011 operates in one of five Power-Down modes, as shown in Table 6-3.
Table 6-3 Clock Operation in Power-Down Modes
Mode Run Core Clocks Core and memory clocks disabled Peripheral Clocks Peripheral clocks enabled Description Device is fully functional
56F8013/56F8011 Data Sheet, Rev. 12 Freescale Semiconductor 79
Table 6-3 Clock Operation in Power-Down Modes (Continued)
Mode Wait Core Clocks Core and memory clocks disabled Peripheral Clocks Peripheral clocks enabled Description Core executes WAIT instruction to enter this mode. Typically used for power-conscious applications. Possible recoveries from Wait mode to Run mode are: 1. Any interrupt 2. Executing a Debug mode entry command during the 56800E core JTAG interface 2. Any reset (POR, external, software, COP) Core executes STOP instruction to enter this mode. Possible recoveries from Stop mode to Run mode are: 1. Interrupt from Timer channels that have been configured to operate in Stop mode (TCx_SD) 2. Interrupt for SCI configured to operate in Stop mode (SCI_SD) 3. Low-voltage interrupt 4. Executing a Debug mode entry command using the 56800E core JTAG interface 5. Any reset (POR, external, software, COP) The user configures the OCCS and SIM to select the relaxation oscillator clock source (PRECS), shut down the PLL (PLLPD), put the relaxation oscillator in Standby mode (ROSB), and put the large regulator in Standby (LRSTDBY). The part is fully operational, but operating at a minimum frequency and power configuration. Recovery requires reversing the sequence used to enter this mode (allowing for PLL lock time). The user configures the OCCS and SIM to enter Standby mode as shown in the previous description, followed by powering down the oscillator (ROPD). The only possible recoveries from this mode are: 1. External Reset 2. Power-On Reset
Stop
Master clock generation in the OCCS remains operational, but the SIM disables the generation of system and peripheral clocks.
Standby
The OCCS generates the 2X system clock at a reduced frequency (200kHz). The PLL and high speed peripheral clocks are disabled and the high-speed peripheral option is not available. System and peripheral clocks operate at 100kHz.
Power-Down
Master clock generation in the OCCS is completely shut down. All system and peripheral clocks are disabled.
The power modes provide additional means to disable clock domains, configure the voltage regulator, and configure clock generation to manage power utilization, as shown in Table 6-3. Run, Wait, and Stop modes provide means of enabling/disabling the peripheral and/or core clocking as a group. Stop disable controls are provided for selected peripherals in the control register so that these peripheral clocks can optionally continue to operate in Stop mode and generate interrupts which will return the part from Stop to Run mode. Standby mode provides normal operation but at very low speed and power utilization. It is possible to invoke Stop or Wait mode while in Standby mode for even greater levels of power reduction. A 200kHz clock external clock can optionally be used in Standby mode to produce the required Standby 100kHz system bus rate. Power-down mode, which selects the ROSC clock source but shuts it off, fully disables the part and minimizes its power utilization but is only recoverable via reset. When the PLL is not selected and the system bus is operating at around 100kHz, the large regulator can be put into its Standby mode (LRSTDBY) to reduce the power utilization of that regulator.
56F8013/56F8011 Data Sheet, Rev. 12 80 Freescale Semiconductor
Resets
All peripherals, except the COP/watchdog timer, run at the system clock (peripheral bus) frequency1, which is the same as the main processor frequency in this architecture. The COP timer runs at MSTR_OSC / 1024. The maximum frequency of operation is SYS_CLK = 32MHz. The only exception is the Quad Timer and PWM, which can be configured to operate at three times the system bus rate using TCR and PCR controls, provided the PLL is active and selected.
6.6 Resets
The SIM supports four sources of reset, as shown in Figure 6-15. 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 the SIM_CTRL register in Section 6.3.1, and the COP reset. The SIM uses these to generate resets for the internal logic. These are outlined in Table 6-4. The first column lists the four primary resets which are calculated. The JTAG circuitry is reset by the Power-On Reset. Columns two through five indicate which reset sources trigger these reset signals. The last column provides additional detail.

All resets are subsequently extended for an additional 32 MSTR_OSC clocks and 64 system clocks as the various internal reset controls are released. Given the normal relaxation oscillator rate of 8MHz, the duration of a POR reset from when power comes on to when code is running is 28S. An external reset generation chip may also be used. Resets may be asserted asynchronously, but they are always released internally on a rising edge of the system clock.

Clocks
6.7 Clocks
The memory, peripheral and core clocks all operate at the same frequency (32MHz max) with the exception of the Quad Timer and PWM peripheral clocks, which have the option (using TCR and PCR) to operate three times faster. The SIM is responsible for stalling individual clocks as a response to various hold-off requests, low power modes, and other configuration parameters. The SIM has access to the following signals from the OCCS module: MSTR_OSC This comes from the input clock source mux of the OCCS. It is the output of the relaxation oscillator or the external clock source, depending on PRECS. It is not guaranteed to be at 50% duty cycle (+ or - 10% can probably be assumed for design purposes). This clock runs continuously, even during resetm and is used for reset generation. The PLL multiplies the MSTR_OSC by 24, to a maximum of 192MHz. The ZSRC field in OCCS selects the active source to be the PLL. This is divided by 2 and postscaled to produce this maximum 96MHz clock. It is used without further division to produce the high-speed (3x system bus rate) variants of the Quad Timer and PWM peripheral clocks. This clock is disabled when ZSRC is selecting MSTR_OSC. The PLL can multiply the MSTR_OSC by 24, to a maximum of 192MHz. When the PLL is selected by the OCCS ZSRC field, the PLL is divided by three and postscaled to produce this maximum 64MHz clock. When MSTR_OSC is selected by the OCCS ZSRC field, MSTR_OSC feeds SYS_CLK_x2 directly. The SIM takes this clock and divides it by two to generate all the normal (1x system bus rate) peripheral and system clocks.
HS_PERF
SYS_CLK_x2
While the SIM generates the ADC peripheral clock in the same way it generates all other peripheral clocks, the ADC standby and conversion clocks are generated by a direct interface between the ADC and the OCCS module. Figure 6-16 illustrates clock relationships to one another and to the various resets as the device comes out of reset. RST is assumed to be the logical AND of all active-low system resets (for example, POR, external reset, COP and Software reset). In the 56F8013/56F8011 architecture, this signal will be stretched by the SIM for a period of time (up to 96 MSTR_OSC clock cycles, depending upon the status of the POR) to create the clock generation reset signal (CLKGEN_RST). The SIM should deassert CLKGEN_RST synchronously with the negative edge of OSC_CLK in order to avoid skew problems. CLKGEN_RST is delayed 32 SYS_CLK cycles to create the peripheral reset signal (PERIP_RST). PERIP_RST is then delayed by 32 SYS_CLK cycles to create CORE_RST. Both PERIP_RST and CORE_RST should be released on the negative edge of SYS_CLK_D as shown. This phased releasing of system resets is necessary to give some peripherals (for example, the Flash interface unit) set-up time prior to the 56800E core becoming active.

Part 7 Security Features
The 56F8013/56F8011 offers security features intended to prevent unauthorized users from reading the contents of the flash memory (FM) array. The 56F8013/56F8011's flash security consists of several hardware interlocks that prevent unauthorized users from gaining access to the flash array. After flash security is set, an authorized user is still able to access on-chip memory if the user purposely includes a subroutine to read and transfer the contents of internal memory via serial communication peripherals, as this code would defeat the purpose of security.
7.1 Operation with Security Enabled
After the user has programmed the flash with his application code, the 56F8013/56F8011 can be secured by programming a security word ($E70A) into program memory location $00 1FF7. This nonvolatile word will keep the device secured through reset and through power-down of the device. Refer to the flash
56F8013/56F8011 Data Sheet, Rev. 12 84 Freescale Semiconductor
Flash Access Lock and Unlock Mechanisms
memory chapter in MC56F8000RM, the 56F8000 Peripheral Reference Manual for details. When flash security mode is enabled, the 56F8013/56F8011 will disable the core EOnCE debug capabilities. Normal program execution is otherwise unaffected.
7.2 Flash Access Lock and Unlock Mechanisms
There are several methods that effectively lock or unlock the on-chip flash.
7.2.1
Disabling EOnCE Access
On-chip flash can be read by issuing commands across the EOnCE port, which is the debug interface for the 56800E CPU. The TCK, TMS, TDO, and TDI pins comprise a JTAG interface onto which the EOnCE port functionality is mapped. When the device 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, but proper implementation of flash security will block any attempt to access the internal flash memory via the EOnCE port when security is enabled.
7.2.2
Flash Lockout Recovery Using JTAG
If the device is secured, one lockout recovery mechanism is the complete erasure of the internal flash contents, including the configuration field, thus disabling security (the protection register is cleared). 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 device on the next reset or power-up sequence. To start the lockout recovery sequence via JTAG, the JTAG public instruction (LOCKOUT_RECOVERY) must first be shifted into the chip-level TAP controller's instruction register. 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. Refer to MC56F8000RM, the 56F8000 Peripheral Reference Manual, for more details, or contact Freescale.
Note: Once the lockout recovery sequence has completed, the user must reset both the JTAG TAP controller and the device to return to normal unsecured operation. Power-on reset will also reset both.
7.2.3
Flash Lockout Recovery Using CodeWarrior
CodeWarrior can unlock a device by selecting the Debug menu, then selecting DSP56800E, followed by Unlock Flash. Another mechanism is also built into CodeWarrior using the device's memory configuration file. The command Unlock_Flash_on_Connect1 in the .cfg file accomplishes the same task as using the Debug menu. This lockout recovery mechanism also includes the complete erasure of the internal flash contents, including the configuration field, thus disabling security (the protection register is cleared).
56F8013/56F8011 Data Sheet, Rev. 12 Freescale Semiconductor 85
7.2.4
Flash Lockout Recovery Without Mass Erase
The user can un-secure a secured device by programming the word $0000 into program memory location $00 1FF7. After completing the programming, both the JTAG TAP controller and the device must be reset in order to return to normal unsecured operation. Power-on reset will also reset both. The user is responsible for directing the device to invoke the flash programming subroutine to reprogram the word $0000 into program memory location $00 1FF7. This is done by, for example, toggling a specific pin, or by downloading a user-defined key through serial interfaces.
Note: Flash contents can only be programmed for 1s to 0s.
7.3 Product Analysis
The recommended method of unsecuring a secured device for product analysis of field failures is via the method suggested in Section 7.2.4. The customer would need to supply Technical Support with the details of the protocol to access the subroutines in flash. An alternative method for performing analysis on a secured device would be to mass-erase and reprogram the flash with the original code, but also either modify the security word or else not program the security word.

Part 9 Joint Test Action Group (JTAG)
9.1 56F8013/56F8011 Information
Please contact your Freescale sales representative or authorized distributor for device/package-specific BSDL information. The TRST pin is not available in this package. The pin is tied to VDD in the package. The JTAG state machine is reset during POR and can also be reset via a soft reset by holding TMS high for five rising edges of TCK, as described in the 56F801X Peripheral User Manual.
Part 10 Specifications
10.1 General Characteristics
The 56F8013/56F8011 are 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 systems, 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. Unless otherwise stated, all specifications within this chapter apply over the temperature range of -40C to 125C ambient temperature over the following supply ranges: VSS = VSSA = 0V, VDD = VDDA = 3.0-3.6V, CL < 50pF, fOP = 32MHz Note: The 56F8011 device is specified to meet Industrial requirements only.
56F8013/56F8011 Data Sheet, Rev. 12 Freescale Semiconductor 93
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.

1. When VDD drops below VEI3.3, an interrupt is generated. 2. When VDD drops below VEI32.5, an interrupt is generated. 3. Power-On Reset occurs whenever the internally regulated 2.5V digital supply drops below 1.8V. While power is ramping up, this signal remains active for as long as the internal 2.5V is below 2.15V or the 3.3V 1/O voltage is below 2.7V, no matter how long the ramp-up rate is. The internally regulated voltage is typically 100mV less than VDD during ramp-up until 2.5V is reached, at which time it self-regulates.
10.2.1
Voltage Regulator Specifications
The 56F8013/56F8011 have two on-chip regulators. One supplies the PLL and relaxation oscillator. It has no external pins and therefore has no external characteristics which must be guaranteed (other than proper operation of the device). The second regulator supplies approximately 2.5V to the 56F8013/56F8011's core logic. This regulator requires an external 2.2F, or greater, capacitor for proper operation. Ceramic and tantalum capacitors tend to provide better performance tolerances. The output voltage can be measured directly on the VCAP pin. The specifications for this regulator are shown in Table 10-8.

1. A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the VIH min of the SCL signal) to bridge the undefined region of the falling edge of SCL. 2. The maximum tHD; DAT has only to be met if the device does not stretch the LOW period (tLOW) of the SCL signal. 3. A Fast mode I2C bus device can be used in a Standard mode I2C bus system, but the requirement tSU; DAT > = 250ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line trmax + tSU; DAT = 1000 + 250 = 1250ns (according to the Standard mode I2C bus specification) before the SCL line is released. 4.

10.15 Equivalent Circuit for ADC Inputs
Figure 10-17 illustrates the ADC input circuit during sample and hold. S1 and S2 are always open/closed at the same time that S3 is closed/open. When S1/S2 are closed & S3 is open, one input of the sample and hold circuit moves to (VREFH-VREFL)/2, while the other charges to the analog input voltage. 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-VREFL)/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.

10.16 Power Consumption
See Section 10.1 for a list of IDD requirements for the 56F8013/56F8011. This section provides additional detail which can be used to optimize power consumption for a given application. 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 currents, Please see http://www.freescale.com for sources operate independently PLL, and voltage references.

Power Consumption
frequency. 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 I/O cell types used on the 56800E reveal that the power-versus-load curve does have a non-zero Y-intercept.
Table 10-20 I/O Loading Coefficients at 10MHz
Intercept 8mA drive 4mA drive 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 10-20 provides coefficients for calculating power dissipated in the I/O 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. 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 eight 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.

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) 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: RJA = RJC + RCA 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)
RJC is device related and cannot be influenced by the user. The user controls the thermal environment to change the case to ambient thermal resistance, RCA. 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 JT PD = Thermocouple temperature on top of package (oC) = Thermal characterization parameter (oC/W) = Power dissipation in package (W)
56F8013/56F8011 Data Sheet, Rev. 12 Freescale Semiconductor 121
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.
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 of the 56F8013/56F8011:
* * Provide a low-impedance path from the board power supply to each VDD pin on the 56F8013/56F8011 and from the board ground to each VSS (GND) pin The minimum bypass requirement is to place 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 tolerances. Ensure that capacitor leads and associated printed circuit traces that connect to the chip VDD and VSS (GND) pins are as short as possible

Electrical Design Considerations
* * *
Bypass the VDD and VSS with approximately 100F, plus the number of 0.1F ceramic capacitors PCB trace lengths should be minimal for high-frequency signals 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. Take special care to minimize noise levels on the VREF, VDDA and VSSA pins Using separate power planes for VDD and VDDA and separate ground planes for VSS and VSSA is recommended. Connect the separate analog and digital power and ground planes as close as possible to power supply outputs. If both analog circuit and digital circuit are powered by the same power supply, it is advisable to connect a small inductor or ferrite bead in serial with both VDDA and VSSA traces. It is highly desirable to physically separate analog components from noisy digital components by ground planes. Do not place an analog trace in parallel with digital traces. It is also desirable to place an analog ground trace around an analog signal trace to isolate it from digital traces. Because the Flash memory is programmed through the JTAG/EOnCE port, SPI, SCI or I2C, the designer should provide an interface to this port if in-circuit Flash programming is desired.
