2.6.4 CAN-Bus Interface

The EVM supports up to six (6) CAN Bus interfaces.

J46CAN16

Each Controller Area Network (CAN) Bus interface is supported on a 3-pin, 2.54mm pitch header. The interface meets ISO 11898-2 and ISO 11898-5 physical standards, and supports CAN and optimized CAN-FD performance up to 8Mbps. Each includes CAN Bus end-point termination. If the EVM is included in a network with more than two nodes, then the termination can need to be adjusted.
