2.3.4 CAN

The LaunchPad can be connected to a CAN bus through J14. GPIO32 and GPIO33 are routed to the on-board TI SN65HVD234 3.3 V CAN Transceiver, U10. By setting S9 to 0, GPIO32 and GPIO33 are routed to the transceiver. If S9 is set to 1, the GPIOs are routed to the BoosterPack connectors. As GPIO33 is also used by the FSI, ensure that R46 is populated with a 0-Ω resistor to connect GPIO33 to the CAN transceiver.
