Color Palette

The color palette is mapped onto addresses (A10–A1) H'100 to H'2FF. Settings can be made for
256 pixels, with 6 bits each for R, G, and B. The color palette is only valid when the GBM bit in
the rendering mode register (REMR) is 0 (8 bits/pixel). When the GBM bit is set to 1 (16
bits/pixel), the color palette values set when the GBM bit is 0 (8 bits/pixel) are lost.
