Color palette
The data written in the display memory is converted into the actual color data output to the LCD panel by the color
palette.
(Pseudo-color mode) The color palette contains 4-bit
× 3-color (R, G, B) (= 12 bits) registers
corresponding to each of the 256 entries addresses.
The correspondence between the display memory data and the color palette entry is established as shown in Table
F2.5 depending on the data width of the display memory. The color palette cannot be used in the direct color mode
(16BPP).
