8.11.14 Raster Coloring Function

An entire screen (raster) can be colored by setting the bits 4 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, 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 raster color register is shown in Figure 8.11.29, the example of

raster coloring is shown in Figure 8.11.30.
