Claims (4)
- 복수의 입력키와, 상기 입력키로부터의 키입력신호를 각각 인코딩하여 출력하는 인코더를 갖는 키입력시스템에 있어서,상기 인코더로 입력되지 아니하는 키입력신호를 발생하는 적어도 하나의 보조입력키와;상기 입력키와 상기 보조입력키가 동시에 선택되는 경우, 상기 인코더에서 코딩되어 출력된 상기 키입력신호와 상기 보조입력키로부터 출력된 키입력신호의 조합에 상응하는 제어를 실행하는 제어부를 포함하는 것을 특징으로 하는 키입력시스템.
- 제 1 항에 있어서,상기 입력키와 상기 보조입력키 중 어느 하나로부터 신호가 입력되는 경우 인터럽트신호를 출력하는 인터럽트발생부를 포함하는 것을 특징으로 하는 키입력시스템.
- 제 1 항에 있어서,상기 입력키만 단독으로 선택된 경우, 상기 마이컴은 상기 인코더에서 코딩되어 출력된 상기 단일키신호에 따라 제어를 실행하는 것을 특징으로 하는 키입력시스템.
- 제 1 항에 있어서,상기 보조입력키만 단독으로 선택된 경우, 상기 마이컴은 상기 보조입력키신호에 따른 제어를 실행하는 것을 특징으로 하는 키입력시스템.
