Abstract
By extending a Basic-CAN controller and/or a Full-CAN controller with a RX filter device, it is possible to compare the CAN identifiers intended for transmission for the CAN controller with those of the received CAN frames. In the case of a match, an interrupt is generated. When no hardware expansion is intended, the RX-FIFO or TX-FIFO of a Full-CAN controller is used for detecting an intrusion.
