Abstract

Embodiments of a device and method are disclosed. A controller area network (CAN) device includes a compare module configured to interface with a CAN transceiver, the compare module having a receive data (RXD) interface configured to receive data from the CAN transceiver, a CAN decoder configured to decode an identifier of a CAN message received from the RXD interface, and an identifier memory configured to store an entry that corresponds to at least one identifier, and 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 when the comparison indicates that the received identifier of the CAN message matches the entry that is stored at the CAN device. The CAN device also includes a signal generator configured to output, in response to the match signal, a signal to invalidate the CAN message.
