1.2 56F8014 Description
The 56F8014 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 56F8014 is well-suited for many applications. The 56F8014 includes many peripherals that are especially useful for industrial control, motion control, home appliances, general purpose inverters, smart sensors, fire and security systems, power management, and medical monitoring 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 compilers to enable rapid development of optimized control applications. The 56F8014 supports program execution from internal memories. Two data operands can be accessed from the on-chip data RAM per instruction cycle. The 56F8014 also offers up to 26 General Purpose Input/Output (GPIO) lines, depending on peripheral configuration. The 56F8014 Digital Signal Controller includes 16KB of Program Flash and 4KB 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 key application-specific feature of the 56F8014 is the inclusion of one Pulse Width Modulator (PWM) module. This module incorporates three complementary, individually programmable PWM signal output pairs and is also capable of supporting five independent PWM functions to enhance motor control functionality. Complementary operation permits programmable dead time insertion, 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 PWM incorporates 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 1/2 (center-aligned mode only) to 16. The PWM module provides reference outputs to synchronize the Analog-to-Digital Converter (ADC) through Quad Timer, Channels 2 and 3.

Award-Winning Development Environment
This Digital Signal Controller also provides a full set of standard programmable peripherals that include one Serial Communications Interface (SCI), one Serial Peripheral Interface (SPI), one Quad Timer, and one Inter-Integrated Circuit (I2C) interface. Any of these interfaces can also be used as General Purpose Input/Outputs (GPIOs).
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 56F8014'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. Figure 1-2 and Figure 1-3 show 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 Part 2 Signal/Connection Descriptions to see which signals are multiplexed with those of other peripherals.
1.4.1
PWM, TMR and ADC Connections
Figure 1-3 shows the over/under voltage connections from the ADC to the PWM and the connections to the PWM from the TMR and GPIO. These signals can control the PWM outputs in a similar manner to the over/under voltage control signals. See the 56F801X Peripheral Reference Manual for additional information. The PWM_reload_sync output can be connected to the TMR channel 3 input and the TMR channels 2 and 3 outputs are connected to the ADC sync inputs. TMR channel 3 output is connected to SYNC0 and TMR channel 2 is connected to SYNC1. SYNC0 is the master ADC sync input that is used to trigger ADCA and ADCB in sequence and parallel mode. SYNC1 is used to trigger ABCB in parallel independent mode. These are controlled by bits in the SIM Control Register; see Section 6.3.1.

Part 3 OCCS
3.1 Overview
This module provides the 2X system clock frequency to the System Integration Module (SIM), which uses it to generate the various chip clocks. This module also produces the OSC_CLK signals 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 master clock frequency and OSC_CLK signals Provides 3X fast peripheral clock to PWM and Timer Safety shutdown feature is available in the event that the PLL reference clock disappears 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 (SYS_CLK2) 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.
56F8014 Technical Data, Rev. 9 26 Freescale Semiconductor Preliminary
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 56F8014 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
On-Chip Memory Program Flash (PFLASH) Unified RAM (ram) 56F8014 8k x 16 2k x 16 Use Restrictions Erase / Program via Flash interface unit and word writes to CDBW Usable by both the Program and Data memory spaces
4.2 Interrupt Vector Table
Table 4-2 provides the 56F8014'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 5.6.11 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 is a slave on the IPBus. It 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). 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, number 0 is the highest priority and number 45 is the lowest.
56F8014 Technical Data, Rev. 9 Freescale Semiconductor Preliminary 43
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 Operating Modes
The ITCN module design contains two major modes of operation:
* * Functional Mode The ITCN is in this mode by default. 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.
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 module has 16 registers.

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.

CLKO Select Register (SIM_CLKOUT)
The CLKO select register can be used to multiplex out selected clocks generated inside the clock
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 56F8014 share their Input/Output (I/O) with GPIO ports. In order to select peripheral or GPIO control, program the GPIOx_PEREN register. 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. 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.

6.4 Clock Generation Overview
The SIM uses master clocks from the OCCS module to produce the peripheral and system (core and memory) clocks. The HS_PERF clock input from OCCS operates at three times the system and peripheral bus rate, or a maximum of 96MHz. The SYS_CLK_x2 clock input from OCCS operates at two times the system and peripheral bus rate, or a maximum of 64MHz. Peripheral and system clocks are generated at a maximum of 32MHz by dividing the SYS_CLK_x2 clock by two and gating it with appropriate power mode and clock gating controls. The PWM and TIMER peripheral clocks can optionally be generated at three times the normal rate at a maximum 96MHz. These clocks are generated by gating the HS_PERF clock with appropriate power mode and clock gating controls. 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). When selected, the relaxation oscillator can be operated at full speed (8MHz), standby speed (400kHz using ROSB), or powered down (using ROPD). An 8MHz MSTR_OSC can be multiplied to 196MHz using the PLL and postscaled to provide a variety of high speed clock rates. Either the postscaled PLL output or MSTR_OSC signal can be selected to produce the master clocks to the SIM. When the PLL is not selected, the HS_PERF clock is disabled and the SYS_CLK_x2 clock is MSTR_OSC. 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 Reference Manual for further details.

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 TMR 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 SYS_CLK_x2 clock at a reduced frequency (400kHz). The PLL and HS_PERF clocks are disabled and the high-speed peripheral option is not available. System and peripheral clocks operate at 200kHz.
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 (SCI and TMR channels) 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 400kHz clock external clock can optionally be used in Standby mode to produce the
56F8014 Technical Data, Rev. 9 Freescale Semiconductor Preliminary 77
required Standby 200kHz 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 200kHz or less, the large regulator can be put into its Standby mode (LRSTDBY) to reduce the power utilization of that regulator. All peripherals, except the COP/watchdog timer, run at the IPBus 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 TMR 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.

6.7 Clocks
The memory, peripheral and core clocks all operate at the same frequency (32MHz max) with the exception of the TMR 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 reset 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 TMR 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 56F8014 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 56F8014 offers security features intended to prevent unauthorized users from reading the contents of the Flash Memory (FM) array. The 56F8014's Flash security consists of several hardware interlocks that prevent unauthorized users from gaining access to the Flash array. Note, however, that part of the security must lie with the user's code. An extreme example would be user's code that includes a subroutine to read and transfer the contents of the internal program to SCI, SPI or another peripheral, 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.
56F8014 Technical Data, Rev. 9 Freescale Semiconductor Preliminary 81
7.1 Operation with Security Enabled
Once the user has programmed the Flash with his application code, the 56F8014 can be secured by programming the security bytes located in the FM configuration field, which are located at the last 9 words of Program Flash. 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 chapter in the 56F801X Peripheral Reference 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 chapter, the 56F8014 will disable the core EOnCE debug capabilities. Normal program execution is otherwise unaffected.
7.2 Flash Access Lock and Unlock Mechanisms
The 56F8014 has several operating functional and debug modes. Effective Flash security must address operating mode selection and anticipate modes in which the on-chip Flash can be read without explicit user permission.
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 TCLK, TMS, TDO, and TDI pins comprise a JTAG interface onto which the EOnCE port functionality is mapped. When the 56F8014 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 a user inadvertently enables security on the 56F8014, the only lockout recovery mechanism is the complete erasure of the internal Flash contents, including the configuration field, and thus disables 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 56F8014 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. 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 the 56F801X 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 (by advancing the TAP state machine to the reset state) and the 56F8014 (by asserting external chip reset) to return to normal unsecured operation.

Introduction
7.2.3
Flash Lockout Recovery using CodeWarrior
CodeWarrior can unlock a device using the command sequence described in Section 7.2.2 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.
7.2.4
Product Analysis
The recommended method of unsecuring a programmed 56F8014 for product analysis of field failures is via the backdoor key access. The customer would need to supply Technical Support 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. To insure that a customer does not inadvertently lock himself out of the 56F8014 during programming, it is recommended that the user program the backdoor access key first, the application code second and the security bytes within the FM configuration field last.

56F8014 Technical Data, Rev. 9 Freescale Semiconductor Preliminary 89
Part 9 Joint Test Action Group (JTAG)
9.1 56F8014 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 56F8000 Peripheral User Manual.
Part 10 Specifications
10.1 General Characteristics
The 56F8014 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 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
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 56F8014 has 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 56F8014's core logic. This regulator requires an external 4.4F, 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. Cb = total capacitance of the one bus line in pF.

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 56F8014. 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]
56F8014 Technical Data, Rev. 9 110 Freescale Semiconductor Preliminary
Power Consumption
A, the internal [static component], is comprised of the DC bias currents for the oscillator, leakage currents, PLL, and voltage references. These sources operate independently of processor state or operating 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)
56F8014 Technical Data, Rev. 9 Freescale Semiconductor Preliminary 115
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 56F8014:
* * Provide a low-impedance path from the board power supply to each VDD pin on the 56F8014 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 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.
* * * *
56F8014 Technical Data, Rev. 9 116 Freescale Semiconductor Preliminary
Electrical Design Considerations
* *
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.
