(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, 7 raster colors can be
obtained.
If the OUT1 pin has been set to raster coloring output, a raster color-
ing signal is always output during 1 horizontal scanning period. This
setting is necessary for erasing a background TV image.
If the R, G, and B pins have been set to output, a raster coloring
signal is output in the part except a no-raster colored character (in
Figure 102, a character “1”) and the character background output
during 1 horizontal scanning period. This ensures that the character
color/the character background color is not mixed with the raster color.
The structure of the raster color register is shown in Figure 101, the
example of raster coloring is shown in Figure 102.
