Abstract

PURPOSE: To shorten the time for data transfer by making it possible to set one-dot display data through the single operation of a microcomputer.
CONSTITUTION: To display a picture for one screen, controller 7 by a microcomputer transfers block switching data to block switching register 8 by using an output port. In this state, since memory-unit addresses of the above-mentined controller 7 corresponds to addresses of one block of picture memory unit 9 respectively, controller 7 transfers address information and data to an address bus and a data bus by a single data transfer instruction and set data for one dot to picture memory unit 9. This data transfer instruction is repeated 32768 times so as to display data for one block. Then, this operation repeated four times with block switching data changes, thereby displaying data for one screen.
