Claims (1)

램(6)에 저장된 정보상태 신호가 멀티플렉서(3)를 통하여 마이크로프로세서(1)및 CRT 콘트롤러(2)에서 제어되어 캐랙터발생롬(12)에 저장된 이미지를 출력시키는 방법에 있어서, 버퍼 2(4)에서 레지스터 1,2(7)(9)에 시작번지 및 끝번지를 저장하여 비교기 1,2(8)(10)로 설정된 범위의 상태 신호가 앤드게이트(A1)를 통하여 인버터(I1)와 연결된 멀티플렉서(11)가 제어되는 임의구간 반전표시 방법.In the method in which the information status signal stored in the RAM 6 is controlled by the microprocessor 1 and the CRT controller 2 through the multiplexer 3 to output an image stored in the character generator ROM 12, the buffer 2 (4). ), The start address and the end address are stored in registers 1,2 (7) (9) so that the status signal of the range set by the comparators 1,2 (8) (10) is transferred through the AND gate A 1 to the inverter I 1. And the multiplexer 11 connected to the arbitrary section inverted display method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
