Abstract
A transceiver for sending and receiving data from a controller area network (CAN) bus is disclosed. The transceiver includes a microcontroller port, a transmitter and a receiver. The transceiver is configured to receive a data frame from a microcontroller via the microcontroller port and to determine if the microcontroller is authorized to send the data frame or part of it based on a message identifier in the data frame and the outcome of the arbitration process. If the microcontroller is unauthorized to send the data, the transceiver is configured to invalidate the data frame and disconnect the microcontroller from the CAN bus for a predetermined period.
