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, U15. By setting S4 to DOWN (on), GPIO32 and GPIO33 are routed to the transceiver. If S4 is set to UP (off), the GPIOs are routed to the BoosterPack connectors. Note that GPIO32 is also a boot mode select pin of the F28002x device and may be pulled up or down, see Section 3.1.7.
