Part 3.14: CAN Communication Interface
There are 2 CAN communication interfaces on the AXU7EV carrier board,
which are connected to the MIO interface of the BANK501 on the PS system
side. The CAN transceiver chip selected TI's SN65HVD232C chip for user CAN
communication services. The connection of the CAN transceiver chip on the
PS side is show as Figure 3-14-1

Part 3.15: 485 Communication Interface
There are two 485 communication interfaces on the AXU7EV carrier board.
The 485 communication port is connected to the IO interface of BANK88 on the
PL system. The 485 transceiver chip selects the MAX3485 chip from MAXIM
