The IDK application card includes two CAN interfaces that are terminated with DB-9 connectors. MCAN0 and MCAN1 signals are used from the application connector of CP card to implement the interface. The option for a 120-ohm termination resistor is placed in between CANH and CANL to match the characteristic impedance of the bus. The STB pin of the of IC is held high by default, and a GPIO control line provided to pull the line low.
