(4) 8-bpp (256-color) mode
One pixel is represented by 8 bits, displayed in 256 colors. This mode is not available for grayscale display.
In this mode, 256 discrete combinations are configured using eight entries in each of the red and green look-
up tables, and four entries in the blue look-up table. Bits 5–7 in one byte of pixel data are used as an index to
the red look-up table, while bits 2–4 and bits 0–1 are used as indices to the green and blue look-up tables,
respectively.
