2.3 CAN Pins

CANH, CANL Pins: The CANH and CANL pins are the differential CAN bus pins, connected to the CAN transceiver and the WUP CAN receiver. A 120Ω termination resistor is required at each end of the CAN bus. The TCAN455x-Q1 CAN communication complies with ISO 11898-1:2015 and the Bosch CAN protocol specification 3.2.1.1.
