At 4-bpp the pixel data is a direct index to the color to be displayed. At this color depth the
Look-Up Table Bank Select bits have no effect on the display colors. For instance: If the
data was 7Bh then the first pixel color would be from the RGB values of the 8th Look-Up
Table address. The second pixel would be the colored by the RGB value at the 12th (0Bh)
Look-Up Table address.
