Abstract

본 발명은 마이콤의 리세트회로에 관한 것으로, 마이콤의 프로그램을 폭주시키는 홀트상태를 방지하는 것을 그 기술적 과제로 한다.The present invention relates to a reset circuit of a microcomputer, and the technical problem is to prevent the hold state of congestion of the microcomputer program.

따라서 본 발명은 직렬로된 단안정멀티바이브레이터를 이용하여 마이콤(5)의 출력포트에서 트리거신호가 출력되지 않을때 마이콤(5)에 리세트를 걸어주고 마이콤(5)은 파워온플래그를 점검하여 바로 메인프로그램을 수행하게 하는 것을 그 요지로 한다.Accordingly, the present invention resets the microcomputer 5 when the trigger signal is not output from the output port of the microcomputer 5 using the monostable multivibrator in series, and the microcomputer 5 checks the power on flag. The main point is to let the main program run.

또한 본 발명은 마이콤을 이용한 제품에서 홀트방지하는 것을 용도로 한다.In addition, the present invention is intended to prevent the hold in the product using the microcomputer.
