(12) Raster Coloring Function
An entire screen (raster) can be colored by switching each of the R,
G, and B pins to MUTE output. R, G, B are controlled with the CRT
port control register; I is controlled with the CRT control register 2;
OUT is controlled with the character size register. 15 raster colors
can be obtained.
If the OUT 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 MUTE signal output, a raster
coloring signal is output in the part except a no-raster colored char-
acter (in Figure 66, a character “O”) during 1 horizontal scanning
period. This ensures that character colors do not mix with the raster
color. In this case, MUTE signal is output from the OUT pin.
An example in which a magenta character “I” and a red character “O”
are displayed with blue raster coloring is shown in Figure 66.
