Abstract
A Controller Area Network, CAN, device comprising: a compare module configured to interface with a CAN transceiver, a CAN decoder configured to decode an identifier of a CAN message received from the RXD input interface; an identifier memory configured to store an entry that corresponds to at least one identifier; compare logic configured to compare a received identifier from a CAN message to the entry that is stored in the identifier memory and to output a match signal upon a match; a signal generator configured to output, in response to the match signal, a signal to invalidate the CAN message, wherein the signal is output from the TXD output interface to the CAN transceiver; and wherein the signal generated by the signal generator provides for one or more dominant bits that are timed so that at a bit immediately following a FDF field or the FDF field bit is made dominant.
