2.4 CAN Second Function Pin Switch

When designing the CAN transceiver circuit or improving the protection level of the
CAN signal cable, consider connecting the second function pin of the CAN signal to the
backplane through the MiniPCIe reserved pin. Design the CAN transceiver circuit by
yourself to improve the system flexibility.
