Abstract
An apparatus is used to control a reset function of an electronic device. The apparatus includes a circuit adapted to monitor a system voltage level and deliver a control signal in response to the system voltage level falling below a first preselected value. A duration controller receives the control signal and delivers a first reset signal for a preselected duration of time after receiving the control signal. A voltage level controller receives the first reset signal, and delivers a second reset signal that persists until the system voltage rises above a second preselected magnitude.
