(3-17) Read Modify Write/End
This instruction sets the Read Modify Write Mode for the column address increment control. In mode of the
Read Modify Write, the column address increases "1" automatically when the Display Data Write Instruction is
executed, but the address does not change when the Display Data Read Instruction is executed. This status is
continued until End instruction execution. When the End instruction (D=1) is input, the column address goes
back to the start address before the Read Modify Write instruction input. This function reduces the load of
MPU for repeating the display data change in the fixed area (ex. cursor blink).
D=”1” to release the Read Modify Write mode and the column address back to the address where the read
modify write mode setting.
