Description

어트리뷰트 제어회로Attribute control circuit

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 고안에 따른 어트리뷰트 제어회로의 블록선도.2 is a block diagram of an attribute control circuit according to the present invention.

Claims (1)

CRT회로 및 CPU를 구비한 어트리뷰트 제어회로에 있어서, CRT회로의 주사 어드레스는 디바이드 어드레스가 어트리뷰트 기능코우드를 갖게하며, 이 주사 어드레스가 비데오 RAM에만 입력되게 하므로, 비데오 RAM이 기능 코우드로 되는 메모리 어드레스 데이터를 문자 발생기에 인가하고, 문자 발생기가 그의 선택단자로 부터 어트리뷰트 제어시 어트리뷰트 신호를 발생시키도록 구성시킨 어트리뷰트 제어회로.In an attribute control circuit having a CRT circuit and a CPU, the scan address of the CRT circuit causes the divide address to have an attribute function code, and this scan address is input only to the video RAM, so that the video RAM becomes a functional code. An attribute control circuit configured to apply data to a character generator and to generate an attribute signal when the character generator controls the attribute from its selection terminal. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
