♦ GCOL[1:0] (x’007F08’, bits 9 and 8) sets the number of colors (2, 4, 8, or 16).
♦ STC[8:0] (x’007F10’, bits 8 to 0) specifies the code of the tile to be displayed.
♦ SPRT (x’007F10’, bit 9) selects tile color palette 1 or 2.
♦ GPT1n (x’007FC0’–x’007FDE) or GPT2n (x’007FE0’–x’007FFE) speci-
fies the colors on the palettes corresponding to the tile data stored in the ROM.
■ To set up the graphics display colors:

♦ GTC[8:0] (GTC bits 8 to 0 in the RAM data) specifies the code of the
tile to be displayed.
♦ GPRT (GTC bit 9 in the RAM data) selects tile color palette 1 or 2.
♦ GPT1n (x’007FC0’–x’007FDE) or GPT2n (x’007FE0’–x’007FFE) speci-
fies the colors on the palettes corresponding to the tile data stored in the ROM.
