2.16.9 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 palette register i (refer to Figure 2.16.30), bits
0 to 2 of the block control register i (refer to Figure 2.16.4) and RC17 of OSD RAM. The setting values for
controlling OUT1, OUT2 and the corresponding output waveform is shown in Figure 2.16.31.

Notes 1: This control is only valid in the OSDS mode. It is invalid in CC/CDOSD/OSDL mode .
2: In the CDOSD mode, coloring is performed for each dot. Accordingly, OUT1 outputs to dots
which bit 6 (CRi_6) of the color pallet register i is set to “0.”
3: OUT2 cannot be output in sprite OSD.
4: ! is an arbitrary value.
