The color/monochrome select (CMS) bit sets the LCD controller to operate in color or
monochrome mode. When CMS=0, color mode is selected. Palette entries are 16 bits wide (5-bits
red, 6-bits green, 5-bits blue), 8 data pins are enabled for single-panel mode, 16 data pins are
enabled for dual-panel mode, and all three dither blocks are used, one each for the red, green, and
Figure 7-18. LCD Data-Pin Pixel Ordering
