2. Fixed shutter mode (External trigger operating mode: Mode 0)
When external trigger signal is high active, after the trigger signal rise edge, the strobe signal start/end
can be set to determine the strobe time.
At the strobe signal falling edge, the internal VD signal is reset and the video data are transmitted.
3. One trigger mode (External trigger operating mode: Mode 1)
When external trigger signal is high active, after the trigger signal rise edge, the strobe signal start/end can be
set to determine the strobe time.
At the flash signal falling edge, the internal VD signal is reset and the video data are transmitted.
