Programmable palettes (8–15) are mapped to AR0–AR63 (8 registers per palette). The
register and bit assignments for Palette # 11 are listed in Figure 24.
Programmable palettes are grouped into 2 banks (palettes 8–11 and 12–15). Palettes in the
bank cannot be modified if another palette from the same bank is displayed. If on-the-fly
palette modifications are required, an interleaving palette bank access must be created.
One palette bank is used to display four colors, and the other bank is used for updates. See
Figure 24.
