Claim Text:
1. A Controller Area Network (CAN) transceiver comprising: a CAN bus interface; a TXD interface; an RXD interface; a transmitter connected between the TXD interface and the CAN bus interface; a receiver connected between the RXD interface and the CAN bus interface; a traffic control system connected between the CAN bus interface, the TXD interface, and the RXD interface to: detect the presence of CAN Flexible Data-rate (FD) traffic on the CAN bus interface; and if the traffic control system detects the presence of CAN FD traffic on the CAN bus interface, change an operating state of the transceiver, where the change in operating state includes disconnecting the CAN bus interface from one of the TXD interface or RXD interface and outputting a controlling message through the RXD interface to block data from being transmitted onto the TXD interface without causing an error condition.
