This module has 2 layers - Layer 0 and Layer 1. Each layer in this display consists of 128 by 64 dots.
Display merging using these 2 layers can be done with the Display ON/OFF command. Refer to 9.2
on page # 8 for details.
Layer 0 has an area of 128x64 dots that starts from top left point defined by the GRAM Start Position
Address. The area of Layer 1 is the next 128x64 dots.
When the value of the GRAM Start Position Address X overflow = 7FH, the next position goes to 00H.
When the value of the GRAM Start Position Address Y overflow = 7FH, the next position goes to 00H.

For example:
If the GRAM Start Position Address is set as X=02H, Y=08H, the area of Layer 0 is as follows;
X=02H,03H,04H……7FH,00H,01H
Y=08H,09H…………46H, 47H
In this case, the area of Layer1 is as follows;
X=02H,03H,04H……7FH,00H,01H
Y=48H,49H…………06H,07H
