Abstract

A transceiver circuit for communicating data over a CAN bus having a first and second bus line the transceiver circuit comprising: a data input port, a data output port, a CAN-bus transceiver unit having a receive data output port for providing data received from the CAN-bus, and a transmit data input port for receiving data to be transmitted to the CAN-bus; a control input port for receiving a control signal indicative of whether transmission of data from this transceiver circuit to the CAN-bus is allowed or prohibited; a filtering circuit adapted for filtering the control signal received on the control input port and for providing a filtered control signal; a logic circuitry adapted for configuring the CAN-bus transceiver unit in receive mode based on the debounced control signal irrespective of ongoing communication on the CAN-bus.
