Abstract: In accordance with an embodiment, a method includes determining whether a frame received from a communication bus is encoded according to a particular communication protocol and is addressed to a particular electronic device; increasing a frame count value when the frame is encoded according to the particular communication protocol and is addressed to the particular electronic device based on the determination, wherein increasing the frame count value comprises increasing a count of a modular arithmetic counter circuit having a first bit depth, and the frame count value is constrained to a modulus value of the modular arithmetic counter circuit; setting a frame count status bit based on comparing the frame count value to threshold values, and transmitting a frame comprising the frame counter status bit over the communication bus, and resetting the frame count value at an end of a monitoring time interval.

Abstract: A device includes a master device, a set of slave devices and a bus. The master device is configured to transmit first messages carrying a set of operation data message portions indicative of operations for implementation by slave devices of the set of slave devices, and second messages addressed to slave devices in the set of slave devices. The second messages convey identifiers identifying respective ones of the slave devices to which the second messages are addressed requesting respective reactions towards the master device within respective expected reaction intervals. The slave devices are configured to receive the first messages transmitted from the master device, read respective operation data message portions in the set of operation data message portions, implement respective operations as a function of the respective operation data message portions read, and receive the second messages transmitted from the master device.

Abstract: A bus microcontroller includes a processor circuit having at least one unit designed for performing one or more functions due to a bus command via a communication bus, a power control circuit adapted to be coupled to a transmitter-receiver circuit for receiving bus messages via the communication bus, and a means for placing at least part of the processor circuit into a reduced-power operating mode without placing the entire processor circuit into the reduced-power operating mode. The power control circuit is designed to evaluate incoming bus messages with respect to an activation bus message containing information on activating at least part of the processor circuit, and to output a corresponding activation control signal. The bus microcontroller also includes means for activating at least a part of the processor circuit that is placed in a reduced-power operating mode, in response to output of an activation control signal of the power control circuit.

Abstract: An electronic device includes a CAN protocol controller, a first communication port configured to be coupled to a first segment of a differential bus, and a second communication port configured to be coupled to a second segment of the differential bus. A first CAN transceiver circuit is coupled to the CAN protocol controller and is configured to receive a first CAN transmission signal and to transmit a first CAN reception signal. The first CAN transceiver is configured to drive a differential voltage at the first segment of the differential bus based on the first CAN transmission signal and to sense a differential voltage at the first segment of the differential bus. The second communication port is enabled in response to a control signal being de-asserted and disabled in response to the control signal being asserted.
