2.16.17 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, 512 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 2.16.51, the example of raster coloring is shown in Figure

2.16.52.

Note: Raster is not output to the area which includes blank area.
