CAN (Controller Area Network) is a high-speed serial network protocol designed to support automotive networks. The dsPIC33CDVC256MP506 integrates a CAN FD Transceiver, ATA6563 (physical layer), which is an essential part of the CAN interface circuit. The reference design includes a CAN interface circuit that can be connected to the CAN network via connector J4. The table here summarizes the pin descriptions of connector J4.
