8.10.15 Raster Coloring Function
An entire screen (raster) can be colored by setting bits 4 to 0 of the
raster color register. Since each of the R, G, B, OUT pins can be
switched to raster coloring output, 8 raster colors can be obtained.
When the character color character background color overlaps with
the raster color, the color (R, G, B, OUT), specified for the character
color character background color, takes priority over the raster color.
This ensures that character color/character background color is not
mixed with the raster color.
The raster color register is shown in Figure 8.10.31, an example of
raster coloring is shown in Figure 8.10.30.
