2.3.3 CAN Interface Connector
The J3 connector provides the CAN_L and CAN_H signals from the onboard CAND-FD transceiver
(TCAN1042HGVDRQ1). These signals can be directly wired to the CAN bus.
Because the digital CAN signals (Tx and Rx) are muxed with the SPI interface signals on the AWR device,
one of the two paths must be selected. This is done by placing the switch S2 on the "CAN" position.
Figure 7 shows the CAN connector.
