2.4.2 CAN-FD Connector(s) [J1] [J2] [J5] [J6]

The EVM supports four (4x) CAN Bus interfaces.

Table 2-8 CAN-FD Interface Assignment
Connector Ref TDA4VM Resource
J1 MCU CAN0
J2 CAN9
J5 CAN0
J6 CAN5

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