Abstract

본 발명은 마이콤의 리세트회로에 관한 것으로, 특히 마이콤의 동작중에 출력단자로 부터 소정의 펄스를 출력되도록 하여 상기 출력단자로부터 소정의 펄스가 출력되지 않으면 마이콤을 리세트를 시켜 이상으로 인한 마이콤의 오동작을 방지하도록 한 마이킴의 리세트회로에 관 한으로, 그 구성은 마이콤(가)으로 부터 출력되는 소정의 펄스를 검출하는 펄스검출수단(나)과, 소정의 리세트신호를 발진하여 출력하는 리세트신호발진수단(다)과, 상기펄스검출수단(나)에서 검출되어 출력되는 펄스신호와, 리세트신호 발진수단(다)에 발진되어 입력되는 리세트신호와를 비교하는 비교판단 수단(라)로 구성하여 상기 마이콤(가)의 오동작시 리세트를 시킬수 있도록 하여서 된 것임.The present invention relates to a reset circuit of a microcomputer, and more particularly, to output a predetermined pulse from an output terminal during the operation of the microcomputer. With regard to the reset circuit of the mikim which prevents a malfunction, the configuration includes pulse detection means (b) for detecting a predetermined pulse output from the microcomputer and a predetermined reset signal for oscillation and output. Comparison signal means for comparing the reset signal oscillating means (C) to be detected, the pulse signal detected and outputted by the pulse detecting means (B), and the reset signal oscillated and inputted to the reset signal oscillating means (C); It consists of (d) to be reset in case of malfunction of Micom.
