External sync signal detection control
Recognition of the transition from the no signal
state to the signal present state.
Sets the sampling period in which the sync signal
can be detected continuously in the horizontal sync
signal period (1H).
The values in parentheses apply when RNE0
(COM51) is 1.
External sync signal detection control
Recognition of the transition from the signal
present state to the no signal state.
Sets the sampling period time in which the sync
signal cannot be detected continuously in the
horizontal sync signal period (1H).
