5.7 CANFD Connector

The CAN connector provides access to the two CAN_FD interfaces (CAN_L and CAN_H signals) from the onboard CAND-FD transceivers. These signals can be directly wired to the CAN bus.

Table 5-3 shows the J3 and J4 connectors that provide the CAN_L and CAN_H signals from the 2 onboard CAND-FD transceivers (TCAN1042HGVDRQ1). These signals are wired to the CAN bus after muxing with the SPI interface signals; one of the two paths must be selected. Two CANs are selected by closing the switch S1.4 (1st position of switch to be ON).
