12.11.9 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 6 of the color code register i (refer to Figure 86), bits
2 and 7 of the block control register i (refer to Figure 63) and RC17 of
OSD RAM. The setting values for controlling OUT1, OUT2 and the
corresponding output waveform is shown in Figure 12.11.29

Notes 1: This control is only valid in the OSD mode. It is invalid in CC/CDOSD mode .
2: In the CDOSD mode, coloring is performed for each dot. Accordingly, OUT1 outputs to dots
which bit 6 of the color pallet register i is set to “0.”
3: OUT2 cannot be output in sprite OSD.
4: ! is an arbitrary value.
