1.2 Device Description

The 56F8356 and 56F8156 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 its low cost, configuration flexibility, and compact program code, the 56F8356 and 56F8156 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 (56F8156 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 56F8356 and 56F8156 support program execution from either internal or external 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 62 General Purpose Input/Output (GPIO) lines, depending on peripheral configuration.

Freescale Semiconductor 7 Preliminary

1.2.1 56F8356 Features

The 56F8356 controller includes 256KB of Program Flash and 8KB of Data Flash (each programmable through the JTAG port) with 4KB of Program RAM and 16KB of Data RAM. It also supports program execution from external memory.
A total of 16KB of Boot Flash is incorporated for easy customer inclusion of field-programmable software routines that can be used to program the main Program and Data Flash memory areas. Both Program and Data Flash memories can be independently bulk erased or erased in pages. Program Flash page erase size is 1KB. Boot and Data Flash page erase size is 512 bytes. The Boot Flash memory can also be either bulk or page erased.
A key application-specific feature of the 56F8356 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 56F8356 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 a part of the 56F8356.

1.2.2 56F8156 Features

The 56F8156 controller includes 256KB of Program Flash, programmable through the JTAG port, with 16KB of Data RAM. It also supports program execution from external memory.
A total of 16KB of Boot Flash is incorporated for easy customer inclusion of field-programmable software routines that can be used to program the main Program Flash memory areas, which can be independently bulk erased or erased in pages. Program Flash page erase size is 1KB. Boot Flash page erase size is 512 bytes. and the Boot Flash memory can also be either bulk or page erased.

1.4 Architecture Block Diagram

Note: Features in italics are NOT available in the 56F8156 device and are shaded in the following figures. The 56F8356/56F8156 architecture is shown in Figure 1-1 and Figure 1-2. Figure 1-1 illustrates how the
56800E system buses communicate with internal memories, the external memory interface and the IPBus Bridge. Table 1-2 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 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.
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.

3.2.1 Crystal 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

When referring to the register definitions for the OCCS in the 56F8300 Peripheral User Manual, use the register definitions without the internal Relaxation Oscillator, since the 56F8356/56F8156 devices do NOT contain this oscillator.

Part 4 Memory Map

4.1 Introduction

The 56F8356 and 56F8156 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 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. Table 4-4 shows the memory map configurations that are possible at reset. After reset, the OMR MA bit can be changed and will have an effect on the P-space memory map, as shown in Table 4-3. Changing the OMR MB bit will have no effect.

The device’s external memory interface (EMI) can operate much like the 56F80x family’s EMI, or it can be operated in a mode similar to that used on other products in the 56800E family. Initially, CS0 and CS1 are configured as PS and DS, in a mode compatible with earlier 56800 devices.
Eighteen address lines are required to shadow the first 192K of internal program space when booting externally for development purposes. Therefore, the entire complement of on-chip memory cannot be accessed using a 16-bit 56800-compatible address bus. To address this situation, the EMI_MODE pin can be used to configure four GPIO pins as Address[19:16] upon reset (only one of these pins [A16] is usable in the 56F8356/56F8156).
The EMI_MODE pin also affects the reset vector address, as provided in Table 4-4. Additional pins must be configured as address or chip select signals to access addresses at P:$10 0000 and above.

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.

Interrupt Vector Table
The location of the vector table is determined by the Vector Base Address (VBA) register. Please see Part
5.6.12 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 56F8156 device.

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 $01_FFF7 and $01_FFFF.

4.7 Peripheral Memory Mapped Registers

On-chip peripheral registers are part of the data memory map on the 56800E series. These locations may be accessed with the same addressing modes used for ordinary Data memory, except all peripheral registers should be read/written using word accesses only.
Table 4-9 summarizes base addresses for the set of peripherals on the 56F8356 and 56F8156 devices.
Peripherals are listed in order of the base address. The following tables list all of the peripheral registers required to control or access the peripherals. Note: Features in italics are NOT available in the 56F8156 device.

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 56F8156) 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.

Introduction

Part 5 Interrupt Controller (ITCN)

5.1 Introduction

The Interrupt Controller (ITCN) module is used to arbitrate between various interrupt requests (IRQs), to signal to the 56800E core when an interrupt of sufficient priority exists, and 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, zero is the highest priority, while number 81 is the lowest.

5.3.1 Normal Interrupt Handling

Once the ITCN has determined that an interrupt is to be serviced and which interrupt has the highest priority, an interrupt vector address is generated. Normal interrupt handling concatenates the VBA and the vector number to determine the vector address. In this way, an offset is generated into the vector table for each interrupt.

5.3.2 Interrupt Nesting

Interrupt exceptions may be nested to allow an IRQ of higher priority than the current exception to be serviced. The following tables define the nesting requirements for each priority level.

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. 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.

5.6.12.2 Fast Interrupt 0 Vector Number (FAST INTERRUPT 0)—Bits 6–0
This value determines which IRQ will be a 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; see Part 5.3.3. 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. Fast interrupts automatically become the highest-priority level 2 interrupt, regardless of their 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 Table 4-5.
