Trigger mode
In this mode video signals begin to accumulate through
synchronization with the external trigger input (12-pin
or 26-pin). The video signals are output after the
specified time has passed. Two modes are usable-the
edge detection mode, which detects the rise edge of the
external trigger signal, and the width detection mode,
which detects the effective length of the trigger. The
period of the external trigger signal cannot be set shorter
than the shutter speed. When Shutter OFF is selected,
the shutter speed is automatically set to 1/15s.

* Only one LVAL is less than 2448CLK during T4 length in order
to adjust the timing. T4 changes by depending on T1.
