Claims (1)
- 외부로부터 입력되는 제어신호에 의해 스위칭 제어되어 입력되는 메모리 맵 입출력 어드레스(A12∼A19),(A9∼A11)와 호스트컴퓨터의 입출력 포트 어드레스(A4∼A11),(A0∼A3)중 어느 한쪽 입력을 선택하도록 된 어드레스 선택기(1)와, 원하는 어드레스 할당범위를 설정하기 위한 8비트 DIP 스위치(3)와, 상기 어드레스 서택기(1)에서 선택된 호스트 어드레스(A12∼19),(A4∼A11)와 상기 DIP 스위치(3)의 8비트 출력신호를 비교하고, 두신호가 동일할 때 소정레벨의 신호를 출력하는 비교기(2)와, 상기 비교기(2)의 출력과 상기 어드레스 선택기(1)에서 선택된 어드레스(A9∼11),(A0∼A3)를 디코딩하여 지정된 범위안에서 할당된 영역의 신호를 발생시키기 위한 디코더(4)와, 그리고 상기 어드레스 선택기(1)에서 선택된 메모리 리드/라이트 신호(-MEMR/-MEMW) 또는 입출력 포트 리드/라이트(-IOR/-IOW) 신호와 상기 디코더(4)의 출력을 조합하여 데이타의 입출력을 제어하기 위한 제어신호(CTL1∼CTLn)를 발생시키는 제어신호 발생부(5)로 구성된 것을 특징으로 하는, 복수개의 어드레싱 방식을 겸용한 인터페이스회로.
