8.11.8 OUT1, OUT2 signals
The OUT1, OUT2 signals are used to control the luminance of the
video signal. The output waveform of the OUT1, OUT2 signals is
controlled by display mode, bit 5 of the block control register i (refer
to Figure 8.11.4) and RA3 of OSD RAM. The setting values for
controlling OUT1, OUT2 and the corresponding output waveform is
shown in Figure 8.11.17.
Note : When OUT2 signal is output, set bit 7 of OSD port control register (refer
to Figure 8.11.28) to “1.”

Notes 1 : FONT/BORDER.....In the OSD mode (Border ON), OUT1 outputs to the area of font and border.
In the OSD mode (Border OFF), OUT1 outputs to only the font area.
AREA..................... OUT1/OUT2 outputs to entire display area of character.
FONT..................... In the CC mode, OUT1 outputs to font area.
2 : When the automatic solid space function is OFF in the CC mode, AREA outputs according to bit 3 of color code.
When it is ON, the solid space is automatically output by a character code regardless of RA3.
