PRECAUTIONS
V. Mask IN (See Figure 4, "An example of V. Mask IN timing")
Driving the V. Mask IN signal to high stops phase-comparison operation.
Adjust the signal so that equalizing pulse of video signal and vertical sync signal are masked.
Masking some parts of horizontal sync signal and video signal do not cause a problem.
However, the rise and fall of V. Mask IN must not occur while horizontal sync signal and
equalizing pulse are low - the time indicated with " l " in Figure 4, for example.
