Abstract
An electronic device includes a CAN protocol controller, a first communication port configured to be coupled to a first segment of a differential bus, and a second communication port configured to be coupled to a second segment of the differential bus. A first CAN transceiver circuit is coupled to the CAN protocol controller and is configured to receive a first CAN transmission signal and to transmit a first CAN reception signal. The first CAN transceiver is configured to drive a differential voltage at the first segment of the differential bus based on the first CAN transmission signal and to sense a differential voltage at the first segment of the differential bus. The second communication port is enabled in response to a control signal being de-asserted and disabled in response to the control signal being asserted.
