by the positive edge of HS. It must be reset by software.
the positive edge of VS. It must be reset by software.
processing in VBI interval is finished. This bit assists the
synchronization of acquisition software to the ACQ-
Timing. It is set by hardware at the beginning of line 24
and the corresponding line of 2nd field. It is reset by
software.
