Abstract
A method and apparatus for managing a controller includes indicating, by a processor of a first device, to the controller of a second device to enter a second power state from a first power state. The controller of the second device responds to the processor of the first device with a confirmation. The processor of the first device transmits a signal to the controller of the second device to enter the second power state. Upon receiving a wake event, the controller of the second device exits the second device from the second power state to the first power state.
