Abstract
An apparatus for use with a Controller Area Network ('CAN') transceiver includes a first input for receiving transmit-data and a second input for receiving receive-data. The transmit-data includes data generated by a CAN controller to cause a CAN transceiver to transmit signalling that represents the transmit-data on the CAN bus and the receive-data indicates signalling from the CAN bus. The apparatus is configured to detect, in the receive-data, one or more fields of a CAN frame. The apparatus is then configured to prevent the CAN transceiver from transmitting the signalling that represents the transmit-data at times corresponding to the detected one or more fields of the CAN frame, thereby preventing an error frame in the transmit-data from being transmitted.
