1-3) When the MSM6562B-xx is used with one MSM5259, up to 28 characters can be
displayed from the first digit to the twenty-eighth digit as shown below:
First digit 2 3 4
00 01 02 03
19 20 21 22 23 24 25 26 27 28
12 13 14 15 16 17 18 19 1A 1B

When the display is shifted by instruction, the correspondence between the
LCD display and DD RAM address changes as shown below:
First digit 2 3 4
(Display shifted to right) 4F 00 01 02
19 20 21 22 23 24 25 26 27 28

1-4) Since the MSM6562B-xx has a DD RAM with a capacity of 80 characters, up to 8 devices
of MSM5259 can be connected to MSM6562B-xx so that 80 characters can be displayed.
