Introduction

SPC56xP54x, SPC56xP60x

20/104

Doc ID 18340 Rev 3

The FlexCAN module provides the following features:

●

Full implementation of the CAN protocol specification, Version 2.0B

–

Standard data and remote frames

–

Extended data and remote frames

–

0 to 8 bytes data length

–

Programmable bit rate as fast as 1 Mbit/s

●

32 message buffers of 0 to 8 bytes data length

●

Each message buffer configurable as Rx or Tx, all supporting standard and extended

messages

●

Programmable loop-back mode supporting self-test operation

●

3 programmable mask registers

●

Programmable transmit-first scheme: lowest ID or lowest buffer number

●

Time stamp based on 16-bit free-running timer

●

Global network time, synchronized by a specific message

●

Maskable interrupts

●

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

●

High immunity to EMI

●

Short latency time due to an arbitration scheme for high-priority messages

●

Transmit features

–

Supports configuration of multiple mailboxes to form message queues of scalable

depth

–

Arbitration scheme according to message ID or message buffer number

–

Internal arbitration to guarantee no inner or outer priority inversion

–

Transmit abort procedure and notification

●

Receive features

–

Individual programmable filters for each mailbox

–

8 mailboxes configurable as a six-entry receive FIFO

–

8 programmable acceptance filters for receive FIFO

●

Programmable clock source

–

System clock

–

Direct oscillator clock to avoid PLL jitter

Safety port (FlexCAN)

The SPC56xP54/60 MCU has a second CAN controller synthesized to run at high bit rates

to be used as a safety port. The CAN module of the safety port provides the following

features:

●

Identical to the FlexCAN module

●

Bit rate as fast as 7.5 Mb at 60 MHz CPU clock using direct connection between CAN

modules (no physical transceiver required)

●

32 Message buffers of 0 to 8 bytes data length

●

Can be used as a third independent CAN module
