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).
