Red/Green
At 8-bpp the lookup scheme gets a little more complicated. Each byte of display data
contains 3 bits of red lookup, 3 bits of green lookup and 2 bits of blue lookup. The 16
addresses of the Look-Up Table are divided into 2 eight-element banks for the red and
green components and 4 four-element banks for the blue component.
