2.11 CAN-FD_A Connector

The J3 connector shown in Figure 2-21 provides the CAN_L and CAN_H signals from the onboard CAN-FD transceiver (TCAN3403DRQ1). These signals are wired to the CAN bus after muxing with the UART-A signals; one of the two paths must be selected. CAN signal paths get connected to PHY by changing the switch S1.4 to off position. CAN standby input can be controlled by toggling S4.1 switch.
