(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, I1, I2, 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, B, I1, and I2 pins have been set to output, a raster color-
ing signal is output in the part except a no-raster colored character
(in Figure 85, a character “1”) during 1 horizontal scanning period.
This ensures that character colors are not mixed with the raster color.
The structure of the raster color register is shown in Figure 84, the
example of raster coloring is shown in Figure 85.
