Overview of the SPC560Px
SPC560P44Lx, SPC560P50Lx
Doc ID 13950 Rev 5
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
–
Zero to eight bytes data length
–
Programmable bit rate up to 1 Mbit/s
●
32 message buffers of zero to eight 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
●
Three 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
–
Eight mailboxes configurable as a six-entry receive FIFO
–
Eight programmable acceptance filters for receive FIFO
●
Programmable clock source
–
System clock
–
Direct oscillator clock to avoid PLL jitter

Safety port (FlexCAN)
The SPC560Px 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 up to 7.5 Mbit/s at 60 MHz CPU clock using direct connection between CAN
modules (no physical transceiver required)
●
32 message buffers of zero to eight bytes data length
●
Can be used as a second independent CAN module
