FlexCAN Module
25.3
The FlexCAN is a communication controller implementing the controller area network (CAN) protocol,
an asynchronous communications protocol used in automotive and industrial control systems. It is a high
speed (1 Mbps), short distance, priority-based protocol that can communicate using a variety of mediums
(such as fiber optic cable or an unshielded twisted pair of wires). The FlexCAN supports both the standard
and extended identifier (ID) message formats specified in the CAN protocol specification, revision 2.0,
part B.
