Abstract
PURPOSE: To program without regarding address relations by one command, by obtaining a desired position by designating simply X and Y positions on a screen in no consideration of a calculating table.
CONSTITUTION: In a CRT display device where input data is inputted to refresh memory 8 and is stored in data register 6 and is displayed on CRT 4, register 5 to accept display data, control part 16 to control the input of input data, and data register 6 to hold display data in register 5 which is subjected to the input control by control part 16 are provided. Further, address counter 9 which converts positions on X and Y axes given from address line 15 to addresses corresponding to memory 8 is provided to input an input/output command from the external to control part 16 through control signal line 20 and obtain addresses corresponding to memory 8, thereby designating an arbitrary position to memory 8.
