ABSTRACT:
This is a method and apparatus for waking up an integrated circuit 10 which has been placed into a low power mode in response to an idle instruction or the like. A plurality of wakeup reset signals 320 and wakeup interrupt signals 330 are provided to wakeup circuitry 300 in order to initiate a wake-up process. Wakeup circuitry 300 conditions signals 320 and signals 330 so that a wake-up process is initiated only when the integrated circuit is in a low power mode; therefore, signals 320 and signals 330 can be used for other purposes when the integrated circuit is not in a low power mode. By such conditioning, no additional pins are required on integrated circuit 10 to provide a plurality of wake-up stimuli.
