3.13 Color Encoder
The decoder generates the video output to ROUT, GOUT and BOUT by integrating window color, border
blackedge, luminance output and color selection output (R, G, B) to form the desired video outputs.
Column 23 ~ column 31 : Reserved.
Note : The register located at column 31 of row 15 is reserved for the testing. Do not program this
byte anytime in normal operation.
