Abstract

본 발명은 키 매트릭스 회로로부터의 키 입력 데이타와 리모콘으로부터의 수신 데이타를 통신 라인의 수를 증가시키지 않고 송신 가능하게 하며, 또 데이타를 수신하는 마이크로컴퓨터의 부담을 경감하는 것을 목적으로 한다.
키 매트릭스 회로(2)를 스캔해서 키 입력 데이타를 추출하는 키 스캔 회로(11)와 데이타를 송신하기 위한 송신 레지스터(14)를 갖춘 키 입력 처리 회로(10)에 리모콘 수신 모듈(6)로부터의 리모콘 엔코드 신호를 해독해서 리모콘 데이터를 생성하는 리모콘 디코더(12)를 설치함과 동시에 키 스캔 회로(11)로부터의 키 입력 데이터와 리모콘 디코더(12)로부터의 리모콘 데이터를 선택적으로 송시 레지스터(14)에 세트하고 두 데이터를 동일한 송신 레지스터(14)로부터 마이크로컴퓨터(3)로 직렬 송신한다.

Claims (1)

  1. 키 매트릭스 회로에 접속되며 이 키 매트릭스 회로를 스캔해서 키 입력 데이타를 얻는 키 스캔 회로, 리모콘 수신 수단으로부터 엔코드 신호를 입력받고 이 엔코드 신호를 해독해서 리모콘 데이타를 생성하는 리모콘 디코더, 및 상기 키 스캔 회로로부터의 키 입력 데이타와 상기 리모콘 디코더로부터의 리모콘 데이타를 선택적으로 입력받고 입력된 데이타를 동기 클럭에 따라 직렬 전송하기 위한 송신레지스터를 구비한 것을 특징으로 하는 키 입력 처리 회로.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
