Abstract

본 발명은 전원 전압 제어를 이용한 마이크로 컨트롤러의 초기화 방법 및 그 장치에 관한 것으로서, 입력된 전원 전압이 소정의 지연회로를 통해 지연되고, 상기 지연회로의 출력을 입력하여 발생되는 초기화 신호에 의해 초기화되는 마이크로 컨트롤러의 초기화 방법은 상기 마이크로 컨트롤러의 정상 동작 여부를 판단하는 단계;및 상기 판단 단계의 결과, 정상적인 동작이 아니면 공급 전원을 차단시키는 단계를 포함하여 초기화 신호뿐 만 아니라 공급 전원 차단에 의해 초기화가 실행된다.The present invention relates to a method for initializing a microcontroller using power supply voltage control, and an apparatus thereof, wherein an input power supply voltage is delayed through a predetermined delay circuit and initialized by an initialization signal generated by inputting an output of the delay circuit. The initialization method of the microcontroller may include determining whether the microcontroller is normally operated; and as a result of the determination, the initialization may be performed not only by the initialization signal but also by the power supply cutoff. Is executed.

따라서, 상술한 바와 같이 본 발명에 의하면, 마이크로 컨트롤러가 초기화 신호를 인식하지 못하는 경우에도 전원 전압을 차단하여 초기화할 수 있는 효과를 갖는다.Therefore, according to the present invention as described above, even if the microcontroller does not recognize the initialization signal has the effect that can be initialized by cutting off the power supply voltage.
