An electronic device is configured for coupling to a communication bus to receive therefrom frames encoded according to a communication protocol. The electronic device comprises a check circuit sensitive to said frames and configured to perform a check (203, 204, 205) as to whether a received frame is encoded according to said communication protocol and is addressed to the electronic device. The electronic device comprises a frame counter circuit configured to count frames received during a monitoring time interval by increasing a frame count value as a result of a positive outcome of said check. The electronic device comprises a comparator circuit configured to set a status bit to a first value indicative of a first operating status of the electronic device as a result of the frame count value being equal (208) to a first threshold value, and to a second value indicative of a second operating status of the electronic device as a result of the frame count value being equal (210) to a second threshold value. The electronic device comprises a controller circuit configured to transmit (212a) over the communication bus a frame comprising the status bit, and configured to reset (214) the frame count value at the end of the monitoring time interval.The frame counter circuit comprises a modular arithmetic counter circuit having a certain bit depth. The frame count value is constrained to a modulus value of the modular arithmetic counter circuit.
