Description

타임 체크 회로Time check circuit

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명에 의한 타임체크회로의 일 실시 회로도.1 is an exemplary circuit diagram of a time check circuit according to the present invention.

제2도는 제1도의 래치회로의 상세회로도.2 is a detailed circuit diagram of the latch circuit of FIG.

제3도는 본 발명에 의한 전탁용 LSI의 타임체크를 위한 흐름도.3 is a flow chart for the time check of the LSI for deposit according to the present invention.

Claims (1)

전탁용 LSI에 있어서 키이 오퍼레이션 중의 1초 발생인가를 판단하기 위한 판단수단과, 이 판단수단에 의해 키이 오퍼레이션 중의 1초발생이면 이를 기억하기 위한 기억수단과, 키이 오퍼레이션 완료직후 상기 기억수단에 1초발생 체크신호가 기억되어 있으면 1초를 카운트함과 동시에 상기 기억수단을 자동 리세트시키기 위한 리세트 수단을 구비한 것을 특징으로 하는 타임체크회로.Judging means for judging whether one second of the key operations has occurred in the LSI for trust, storage means for storing this one second of the key operations by the judging means, and one second in the storage means immediately after completion of the key operation. And a reset means for counting one second when the generation check signal is stored, and for automatically resetting the storage means. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
