MPC561/MPC563

PRODUCT BRIEF

MOTOROLA

4

• Alternate reference input (ALTREF), with control in the conversion command word (CCW)

Three CAN 2.0B Controller (TouCAN) Modules

• Three TouCAN modules (TOUCAN_A, TOUCAN_B, TOUCAN_C)

• Each TouCAN provides the following features:

— 16 message buffers each, programmable I/O modes

— Maskable interrupts

— Independent of the transmission medium (external transceiver is assumed)

— Open network architecture, multi-master concept

— High immunity to EMI

— Short latency time for high-priority messages

— Low-power sleep mode, with programmable wake-up on bus activity

— TOUCAN_C pins are shared with MIOS14 GPIO or QSMCM

Queued Serial Multi-Channel Module (QSMCM)

• One queued serial module with one queued SPI and two SCIs (QSMCM)

• QSMCM matches full MPC555 QSMCM functionality

• Queued SPI

— Provides full-duplex communication port for peripheral expansion or inter-processor commu-

nication

— Up to 32 preprogrammed transfers, reducing overhead

— Synchronous serial interface with baud rate of up to system clock / 4

— Four programmable peripheral-selects pins:

— Support up to 16 devices with external decoding

— Support up to eight devices with internal decoding

— Special wrap-around mode allows continuous sampling of a serial peripheral for efficient inter-

facing to serial analog-to-digital (A/D) converters

• SCI

— UART mode provides NRZ format and half- or full-duplex interface

— 16 register receive buffers and 16 register transmit buffers on one SCI

— Advanced error detection and optional parity generation and detection

— Word-length programmable as eight or nine bits

— Separate transmitter and receiver enable bits, and double buffering of data

— Wake-up functions allow the CPU to run uninterrupted until either a true idle line is detected,

or a new address byte is received

Peripheral Pin Multiplexing (PPM) PPM

• Synchronous serial interface between the microprocessor and an external device

• Four internal parallel data sources can be multiplexed through the PPM

— TPU3_A: 16 channels

— TPU3_B: 16 channels

— MIOS14: 12 PWM channels, 4 MDA channels

— Internal GPIO: 16 general-purpose inputs, 16 general-purpose outputs

• Software configurable stream size

• Software configurable clock (TCLK) based on system clock

• Software selectable clock modes (SPI mode and TDM mode)

• Software selectable operation modes

— Continuous mode

— Start-transmit-receive (STR) mode

• Software configurable internal modules interconnect (shorting)
