Gamma look-up table
the same time is 16. The AT3210 has a 4-bit to 5-bit look-up table. User can select the desired

height of the panel size are both limited to 160. The display window is also adjustable by
setting the (XWS,YWS) and ending (XWE,YWE). The column number indicated by the XWS or
the XWE is (XWS*8) or (XWE*8). The panel size indicated by the XP is (XP*8). The XWS and
XWE must be smaller than the XP and the YWS and YWE must be smaller than YP. The
internal column counter will automatically increase between the XWS and XWE. The internal
row counter will automatically increase between the YWS and YWE. Any write operation
outside the window will not be displayed and overlaid by the background color.
Address counter
will automatically increase according to the window setting during successive read/wrire of
display memory (RS pin=’1’) if the ACINC command is set to ‘1’. User can directly write to the
counters by the COLADR and ROWADR command. These counters will be update when the
