4.5.3.12 256 × 16-bit Color Palette Register (PALETTE)
The PALETTE Registers contain 256 palette entries organized as 128 locations of two
entries per word. TFT displays use 12 of the palette entry bits. Each word location contains
two palette entries. This means that 128 word locations are used for the palette. The color
that is displayed is based on the setting of bit [8] of the Control Register (see Section 4.5.6.2).
For color STN displays, only bits [4:1] of red, blue, and green palettes are used. For mono-
chrome STN displays, only the red palette bits [4:1] are used.
