8.11.16 Raster Coloring Function
An entire screen (raster) can be colored by setting the bits 6 to 0 of
the raster color register. Since each of the R, G, B, OUT1, and OUT2
pins can be switched to raster coloring output, 64 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 the character color/the character
background color is not mixed with the raster color.
The raster color register is shown in Figure 8.11.54, the example of
raster coloring is shown in Figure 8.11.55.
