4.2.1 Gray Shade Modes
Gray shade (monochrome) modes are defined by the Color/Mono Panel Select bit
(REG[10h] bit 6). When this bit is set to 0, the value output to the panel is derived solely
from the green component of the LUT.
1 bpp gray shade
The 1 bpp gray shade mode uses the green component of the first 2 LUT entries. The
remaining indices of the LUT are unused.
2 bpp gray shade
The 2 bpp gray shade mode uses the green component of the first 4 LUT entries. The
remaining indices of the LUT are unused.
