Abstract
A data processing system includes multiple powered domains which communicate using a bridge. The bridgeincludes first bridge circuitrywithin a first power domain and second bridge circuitrywithin a second power domain. The first bridge circuitryand the second bridge circuitryexchange intra-bridge power control signals which serve to control management of the communication channel through the bridgeto adopt a communication open state or a communication quiesced state independent of whether either side of the bridge is in a power-active state or a power-inactive state.
