ABSTRACT:
A character generator driven by a microcomputer and providing latched outputs is disclosed. Flexibility in character size and character array positioning on the video display is provided for in this 60-character display generator integrated circuit. A plurality of latched outputs permits the character generator to perform additional functions while reducing the number of dedicated microcomputer outputs required to perform these and similar functions. The character generator is particularly adapted for use in a television receiver where characters are displayed on the face of the cathode ray tube.
