Note that the display area on the LCD is display digits 1 to 16 on the first line when a display technique is 5 × 7, 5 × 8,
or 5 × 9 dots, and it is display digits 1 to 13 on the first line when a display technique is 6 × 7, 6 × 8, or 6 × 9 dots.
Note ∗2: The DCRAM address is expressed in hexadecimal.
