REG [20h] Active Window Right Register (AWRR)
Note:
REG[20h, 30h, 40h, and 50h] are used to dominate an active window for line/row changing when writing
data. Users can use these four registers to set the left/right/top/bottom boundary of active window. When
data goes beyond the right boundary of it, the cursor will automatically change the next line to write data. It
will move to the left boundary of new line in active window. When the data comes to the right-bottom corner,
the next write will cause the cursor to move to the left-top corner.
REG [21h] Display Window Width Register (DWWR)
Note:
REG[21h, 31h] are used to set Display Window Resolution. Users can set the viewing scope of Display
Data RAM. Column width (DWWR) of RA8806 can be set between 0h ~ 27h, and Row height (DWHR) can
be set between 0h ~ EFh.
REG [30h] Active Window Bottom Register (AWBR)
REG [31h] Display Window Height Register (DWHR)

If LCD panel resolution is 320x240, the value of the register is:
Active Window Bottom Position
Note: AWBR must be equal or larger then AWTR, and less or equal
then the value EFh(239 in decimal)
Display Window Height Position
If LCD panel resolution is 320x240, the value of the register is:
Segment-Right = (Segment Number / 8) – 1
( 320 / 8 ) - 1 = 39 = 27h
Common_ Height = LCD Common Number –1
240 – 1 = 239 = EFh
