Abstract:
A method and apparatus is described for computing a duration of a reduced power consumption state. A time of exiting from the reduced power consumption state is read prior to an execution of an interrupt routine. The read time of exiting is then stored in a register and a calculation of a reduced power consumption state duration may be performed.
