18. CAN Module

This document is under development and its contents are subject to change.

The CAN module provides the following CAN interrupts.

• CANi Successful Reception Interrupt ( i = 0, 1)

• CANi Successful Transmission Interrupt

• CAN0/1 Error Interrupt: Error Passive State

Error BusOff State

Bus Error (this feature can be disabled separately)

• CAN0/1 Wake-up Interrupt

When the CPU detects the CANi successful reception/transmission interrupt request, the MBOX bit in the

CiSTR register must be read to determine which slot has generated the interrupt request.
