(12) Read Modify Write
This command is used together with the end command. Once this command is entered, the column address can be
incremented by 1 only using the display data write command instead of being changed using the display read command.
This state is held until the end command is entered. When the end command is entered, the column address returns to
the address when the read modify write command is entered. This function can reduce the load of the MPU when
repeatedly changing data for a specific display area such as a blinking cursor.
* The commands other than Display Data Read/Write can be used even in Read Modify Write mode. However, the
