1.2 Device Description
The 56F8345 and 56F8145 are members of the 56800E core-based family of controllers. Each combines,
on a single chip, the processing power of a Digital Signal Processor (DSP) and the functionality of a
microcontroller with a flexible set of peripherals to create an extremely cost-effective solution. Because
of their low cost, configuration flexibility, and compact program code, the 56F8345 and 56F8145 are
well-suited for many applications. The devices include many peripherals that are especially useful for
motion control, smart appliances, steppers, encoders, tachometers, limit switches, power supply and
control, automotive control (56F8345 only), 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 56F8345 and 56F8145 support program execution from internal memories. Two data operands can be
accessed from the on-chip data RAM per instruction cycle. These devices also provide two external
dedicated interrupt lines and up to 49 General Purpose Input/Output (GPIO) lines, depending on peripheral
configuration.
1.2.156F8345 Features
The 56F8345 controller includes 128KB of Program Flash and 8KB of Data Flash (each programmable
through the JTAG port) with 4KB of Program RAM and 8KB of Data RAM. A total of 8KB of Boot Flash
is incorporated for easy customer inclusion of field-programmable software routines that can be used to
56F8345 Technical Data, Rev. 14.0
Freescale Semiconductor7
Preliminary
Page 8
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 56F8345 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 reference outputs to
synchronize the Analog-to-Digital Converters through two channels of Quad Timer C.
The 56F8345 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 alert when no shaft motion is detected.
Each input is filtered to ensure only true transitions are recorded.
This 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 also a part of the 56F8345.
1.2.256F8145 Features
The 56F8145 controller includes 128KB of Program Flash, programmable through the JTAG port, and
8KB of Data RAM. A total of 8KB of Boot Flash is incorporated for easy customer inclusion of
field-programmable software routines that can be used to program the main Program Flash memory area.
The Program Flash memory can be independently bulk erased or erased in pages; Program Flash page
erase size is 1KB. The Boot Flash page erase size is 512 bytes; Boot Flash memory can also be either bulk
or page erased.
A key application-specific feature of the 56F8145 is the inclusion of one Pulse Width Modulator (PWM)
module. This module incorporates three complementary, individually programmable PWM signal output
pairs and can also support six independent PWM functions to enhance motor control functionality.

internal interrupt controller is also a part of the 56F8145.
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.

1.4 Architecture Block Diagram
Note:Features in italics are NOT available in the 56F8145 device and are shaded in the following figures.
The 56F8345/56F8145 architecture is shown in Figure 1-1 and Figure 1-2. Figure 1-1 illustrates how the
56800E system buses communicate with internal memories and the IPBus Bridge. Table 1-2 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 Part 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’s Manual for clarification on the operation of all three of these
peripherals.

2.2 Signal Pins
After reset, each pin is configured for its primary function (listed first). Any alternate functionality must
be programmed.
EMI is not functional in this package; since only part of the address/data bus is bonded out, use as GPIO
pins.
Note:Signals in italics are NOT available in the 56F8145 device.
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.

3.2 External Clock Operation
The 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.
3.2.1Crystal Oscillator
The internal oscillator is designed to interface with a parallel-resonant crystal resonator in the frequency
range specified for the external crystal in Table 10-15. 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.
56F8345 Technical Data, Rev. 14.0

Part 4 Memory Map
4.1 Introduction
The 56F8345 and 56F8145 devices are 16-bit motor-control chips based on the 56800E core. These parts
use a Harvard-style architecture with two independent memory spaces for Data and Program. On-chip
RAM and Flash memories are used in both spaces.
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 each device are summarized in Table 4-1. Flash memories’ restrictions are
identified in the “Use Restrictions” column of Table 4-1.

4.2 Program Map
The Program memory map is located in Table 4-4. The operating mode control bits (MA and MB) in the
Operating Mode Register (OMR) control the Program memory map. At reset, these bits are set as indicated
in Table 4-2.
EXT_BOOT = EMI_MODE = 0 and cannot be changed in the 56F8345 or 56F8145.

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 Part
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 contain branch or
JMP instructions. All other entries must contain JSR instructions.
Note: PWMA, FlexCAN, Quadrature Decoder 1, and Quad Timers B and D are NOT available on the
56F8145 device.

1. Two words are allocated for each entry in the vector table. This does not allow the full address range to be referenced
from the vector table, providing only 19 bits of address.
2. If the VBA is set to $0200 (or VBA = 0000 for Mode 1, EMI_MODE = 0), the first two locations of the vector table are
the chip reset addresses; therefore, these locations are not interrupt vectors.

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 56F8300 Peripheral User Manual. These configuration parameters are located
between $00_FFF7 and $00_FFFF.

4.8 Factory Programmed Memory
The Boot Flash memory block is programmed during manufacturing with a default Serial Bootloader
program. The Serial Bootloader application can be used to load a user application into the Program and
Data Flash (NOT available in the 56F8145) memories of the device. The 56F83xx SCI/CAN Bootloader
User Manual (MC56F83xxBLUM) provides detailed information on this firmware. An application note,
Production Flash Programming (AN1973), details how the Serial Bootloader program can be used to
perform production Flash programming of the on-board Flash memories as well as other potential
methods.
Like all the Flash memory blocks, the Boot Flash can be erased and programmed by the user. The Serial
Bootloader application is programmed as an aid to the end user, but is not required to be used or maintained
in the Boot Flash memory.
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
•Drives initial address on the address bus after reset
For further information, see Table 4-5, Interrupt Vector Table Contents.
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.
5.3.1Normal 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.

Functional Description
5.3.2Interrupt 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.
Fast interrupts are described in the DSP56F800E 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. Also, the IRQA
and IRQB
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
signals automatically become low-level sensitive in these modes, even if the control register bits
can wake it up.

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.
This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2.
They are disabled by default.
•00 = IRQ disabled (default)
•01 = IRQ is priority level 0
•10 = IRQ is priority level 1
•11 = IRQ is priority level 2

5.6.30.1 Interrupt (INT)—Bit 15
This read-only bit reflects the state of the interrupt to the 56800E core.
•0 = No interrupt is being sent to the 56800E core
•1 = An interrupt is being sent to the 56800E core
These read-only bits reflect the state of the new interrupt priority level bits being presented to the 56800E
core at the time the last IRQ was taken. This field is only updated when the 56800E core jumps to a new
interrupt service routine.
Note:Nested interrupts may cause this field to be updated before the original interrupt service routine can
read it.
•00 = Required nested exception priority levels are 0, 1, 2, or 3
•01 = Required nested exception priority levels are 1, 2, or 3
•10 = Required nested exception priority levels are 2 or 3
•11 = Required nested exception priority level is 3
5.6.30.3 Vector Number - Vector Address Bus (VAB)—Bits 12–6
This read-only field shows the vector number (VAB[7:1]) used at the time the last IRQ was taken. This
field is only updated when the 56800E core jumps to a new interrupt service routine.
Note:Nested interrupts may cause this field to be updated before the original interrupt service routine can
read it.
5.6.30.4 Interrupt Disable (INT_DIS)—Bit 5
This bit allows all interrupts to be disabled.
•0 = Normal operation (default)
•1 = All interrupts disabled
5.6.30.5 Reserved—Bit 4
This bit field is reserved or not implemented. It is read as 1 and cannot be modified by writing.
5.6.30.6 IRQB State Pin (IRQB STATE)—Bit 3
This read-only bit reflects the state of the external IRQB pin.
5.6.30.7 IRQA State Pin (IRQA STATE)—Bit 2
This read-only bit reflects the state of the external IRQA pin.

5.6.30.8 IRQB Edge Pin (IRQB Edg)—Bit 1
This bit controls whether the external IRQB interrupt is edge- or level-sensitive. During Stop and Wait
modes, it is automatically level-sensitive.
•0 = IRQB interrupt is a low-level sensitive (default)
•1 = IRQB
interrupt is falling-edge sensitive.
5.6.30.9 IRQA Edge Pin (IRQA Edg)—Bit 0
This bit controls whether the external IRQA interrupt is edge- or level-sensitive. During Stop and Wait
modes, it is automatically level-sensitive.
•0 = IRQA interrupt is a low-level sensitive (default)
•1 = IRQA
interrupt is falling-edge sensitive.
5.7 Resets
5.7.1Reset Handshake Timing
The ITCN provides the 56800E core with a reset vector address whenever RESET is asserted. The reset
vector will be presented until the second rising clock edge after RESET is released.
5.7.2ITCN After Reset
After reset, all of the ITCN registers are in their default states. This means all interrupts are disabled except
the core IRQs with fixed priorities:
•Illegal Instruction
•SW Interrupt 3
•HW Stack Overflow
•Misaligned Long Word Access
•SW Interrupt 2
•SW Interrupt 1
•SW Interrupt 0
•SW Interrupt LP
These interrupts are enabled at their fixed priority levels.

Part 6 System Integration Module (SIM)
6.1 Introduction
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
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 the 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 done
explicitly
— 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
clocks (phased release of reset) for reset, except for POR, which is 2
•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
operations. Reset delay will be 3 x 32
21
clock cycles.
