23. CAN Module
CAN (Controller Area Network) module included in the M32C/87 Group is a Full CAN module, supporting CAN
Specification 2.0 Part B. Two channels, CAN0 and CAN1, can be used. Table 23.1 lists CAN module specifications of
the CAN0 and CAN1 channels.

selected from the CAN bus bit clock divided by 1, 2, 3, or 4
The BasicCAN function can be used with the CANi message slots 14 and 15
A transmit request is aborted
Frame transmitted by the CAN module is received by the same CAN module
The CAN module is forcibly placed in an error active state by an error counter

The CAN module does not retransmit data even if arbitration lost or transmit error
causes a transmit failure
