Claim:
1. A method, comprising: setting an operating parameter for a power rail, wherein the operating parameter comprises a power value; releasing, with a power management circuit, a processor to start; storing a default operating parameter for the power rail, wherein the default operating parameter comprises a default power value; receiving a runtime operating parameter for the power rail and modifying the operating parameter for the power rail according to the runtime operating parameter, wherein the runtime operating parameter comprises a runtime power value; and in response to a reset control signal from the processor, transitioning the operating parameter for the power rail from the runtime operating parameter to the default operating parameter, wherein the transitioning comprises transitioning the power value for the power rail from the runtime power value to the default power value, and wherein the power value for the power rail is maintained at a value greater than zero throughout the transition.
