The CAN_PORT connector provides an interface to the MSCAN12 on the microcontroller. This port provides a CAN transceiver device. See the schematic drawing and the MC68HC912D60 data sheet for information on using this peripheral.

RxCAN1-3 can be added to supply CAN port bus terminations as required (see schematic).
