Abstract
PURPOSE: To secure the cursor display to the display divided into optional units through a simple method without providing the cursor coincidence detection circuit but by adding the cursor code bits into the refresh memory.
CONSTITUTION: The display unit displays both the display character of the data to be displayed and the cursor which is added to the characters when necessary to the address designated. In such display unit, refresh 10 memory 20 with cursor bit is provided to control circuit 10 which delivers the address and the data with the output of data register 9, cursor register 11, column address counter 3 and line counter 5 used as the input. And then the display character code and the cursor bits are read out at one time when the address is designated to the display character code through control circuit 10. Thus, the cursor display is given to the screen divided into plural units.
