Abstract
The present invention is related to a system reset device setting the reset status of a system in response to a reset signal. The system reset device according to the present invention includes a power-stability detecting circuit for detecting the stability of a power signal generated by a power source and provided for the system, an oscillation-stability detecting circuit for detecting the stability of an oscillation signal generated by an oscillator and provided for the system, and a level-control circuit electrically connected to the power-stability detecting circuit and the oscillation-stability detecting circuit for controlling a level state of the rest signal in response to the stability of the power signal and the oscillation signal. The level-control circuit includes an OR gate, an AND gate, and an S-R latch for performing the level state control of the reset signal.
