Abstract
A voltage sensing circuit is used to determine when the current supply to a processing unit is under transition. During power up transitions, the voltage sensing circuit allows the processing unit to reset normally. During power down transitions, the voltage sensing circuit prevents the processing unit from resetting until a predetermined procedure has been completed, thereby assuring an orderly shutdown.
