19.3.49 Color Palette 2 Register 000 to 255 (CP2_000R to CP2_255R)
The color palette 2 registers 000 to 255 (CP2_000R to CP2_255R) are a group of 256 registers
which set six bits for each of the RGB components of a color, and are used as a color palette
capable of displaying 256 colors among 260,000 possible colors. Bits 31 to 24 are used as a blend
ratio. The values are valid for 8 bits/pixel data display.
For details of color palette operation, refer to section 19.4.8, Color Palettes.
Values are retained during power-on reset and manual reset.
