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.
