External Trigger Exposure Mode (Trigger Level)
In external trigger exposure mode (Trigger Level), the exposure time is
determined by the high trigger pulse time, each exposure starts with the rising edge
and the line period is determined by the time rising edge to rising edge of trigger
pulse. The range of programmable exposure time, the timing chart of the exposure
and the readout are shown below.
