Abstract
본 발명은 시스템의 리세트 시간 가변 장치에 관한 것으로, 종래에는 외부로부터 리세트 신호를 인가함에 의해 초기의 리세트 시간을 정확히 측정할 수 없음으로 파워 다운 모드가 설정되는 경우 항상 외부의 리세트 단자로 리세트 신호를 인가하여야만 파워 다운 모드를 해제할 수 있는 단점이 있다. 이러한 종래의 문제점을 개선하기 위하여 본 발명은 임의로 리세트 시간을 설정하여 초기의 리세트 시간을 측정함에 의해 임의로 설정된 리세트 시간과 일치하면 클럭을 발생시키도록 구성한 것으로, 본 발명은 초기의 리세트 시간을 임의로 설정된 리세트 시간과 비교함에 의해 정확히 측정할 수 있음으로 초기에 리세트 신호를 충분히 인가하여 시스템의 오동작을 방지할 수 있다.The present invention relates to a device for varying the reset time of a system, and in the related art, the initial reset time cannot be accurately measured by applying a reset signal from an external source. The power down mode can be released only by applying a reset signal. In order to solve such a conventional problem, the present invention is configured to generate a clock when the reset time is coincident with the arbitrarily set reset time by measuring the initial reset time. Since the time can be accurately measured by comparing the reset time with an arbitrarily set reset time, it is possible to prevent the malfunction of the system by sufficiently applying the reset signal at the beginning.
