(21) Read Modify Write
This command is paired with end command for use. If this command is entered, the column address is not changed by
the Display Data Read command. It can be incremented +1 by the Display Data Read command alone. This state s
retained until the End command is input. If the End command is input, the column address goes back to the address
when the Read Modify Write command is input. This function reduces the MPU loads when changing the data repeated
in the specific display area such as blinking cursor.
