Abstract
A device for allowing a CAN 2.0B controller to participate passively in CAN FD communication is described. The device is configured to identify whether a frame on RXD is a CAN FD frame and, in dependence upon identifying that the frame is a CAN FD frame, to replace a section of the CAN FD frame, including the data phase of the CAN FD frame, with substitute data having a format which complies with CAN 2.0B. The device may be included in a CAN transceiver.
