ABSTRACT:
An integrated semiconductor circuit for an electronic control unit has a microcontroller with a bus protocol function for communicating with other microcontrolled control units via a Controller Area Network (CAN) by way of a two-wire bus. The invention includes a bus-fault-tolerant transceive function which permits communication even when a bus fault is present. A bus fault recognition and response device disconnects the bus from its normal connections and alters its termination characteristics when a fault is detected.
