4.8.3 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.

Note:
The timing of reading out does one scanning delay from the exposure.
