Noise ignoring circuit setting for sync signal
recognition for the no signal to signal present
transition
If more than the number of horizontal signals
shown at the left are input during a 1H period, the
circuit recognizes a no signal state.
Synchronization discrimination
Selects the clock used to delimit the HSYNI signal.
Changes the judgment criterion values for sync
signal recognition for the no signal to signal
present transition. (COM50)
