(9) 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 bit 4 of the color code 1 (refer to Figure 65), bits 2 and
7 of the block control register (refer to Figure 50). The setting values
for controlling OUT1, OUT2 and the corresponding output waveform
is shown in Figure 66.
