The J1 and J2 connectors shown in Table 2-8 provide the CAN_L and CAN_H signals from the onboard CAND-FD transceiver (TCAN1042HGVDRQ1) and CAN transceiver (SN65HVDA540QDR) independently, as shown in Figure 2-22. 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 (1st position of switch to be ON).
Pin Description | Device Interface | Connector on Board |
---|---|---|
SPI_CS1 SPI_CLK1 | CAN2_TX CAN2_RX | J2 pin 1 (CAN2 corresponds to Regular CAN) J2 pin 3 |
MISO_1 MOSI_1 | CAN1_TX CAN1_RX | J1 pin 1 (CAN1 corresponds to CANFD) J1 pin 3 |
Figure 2-22 shows the CAN connectors.
