8.10.9 Raster Coloring Function
An entire screen (raster) can be colored by setting the CRT port con-
trol register. Since each of the R, G, B, OUT1, and OUT2 pins can be
switched to raster coloring output, 8 raster colors can be obtained.
When the character color/the character background color overlaps
with the raster color, the color (R, G, B, OUT1, OUT2), specified for
the character color/the character background color, takes priority of
the raster color. This ensures that character color/character back-
ground color is not mixed with the raster color.
The example of raster coloring is shown in Figure 8.10.18.
