An integrated circuit device, such as a processor initiates a transition to a first power management state. The device then receives a request to exit the first power management state and, in response exits the first power management state at the highest of a reference operating voltage, such as a minimum operating voltage, and a current voltage. For one aspect, an analog to digital converter may be used to determine the current voltage level. Further, for one aspect the first power management state may be a deeper sleep (C) state, and the processor may quickly exit to a Cstate in response to a bus event such as a bus snoop.
