226 Programming Graphics
$FF14 Bits 7-3 determine location of luminance/color memory (bits
15-11).
$FF19 Border luminance and color.
The bit map displayed is determined by bit-map memory. The luminances of both
colors are determined by color memory (normally $0800-$0BE7). Color for both
colors is determined by screen memory (normally $0C00-$0FE7).
Multicolor Bit Map
$FF06 Set bit 5 for bit-map mode.
$FF07 Set bit 4 for multicolor mode.
$FF12 Bit 2 determines RAM (0) or ROM (1).
Bits 5-3 determine location of bit map (bits 15-13).
SFF14 Bits 7-3 determine location of luminance/color memory (bits
15-11).
$FF15 Background 0 luminance and color.
$FF16 Background 1 luminance and color.
$FF19 Border luminance and color.
The bit map displayed is determined by bit-map memory. The luminances of both
colors are determined by color memory (normally $0800-$0BE7). Color for both
local colors is determined by screen memory (normally $0C00-$0FE7).
