Composite sync output. May be either
the raw output of sync slicer, or
regenerated signal from internal pulse
generators. If raw slicer output is
selected, then signals disappear when
input signal disappears. If regenerated
output is selected, then signal is
always present regardless of input
conditions. Preset modes produce
regenerated sync.
This is a dual mode pin. User may
