4.8.2 External Trigger Exposure Mode (External trigger edge)

In external trigger exposure mode (Trigger Edge), the exposure time is determined

by the setting through serial communication, each exposure starts with the rising

edge and the line period is determined by the time from rising edge to rising edge of

the trigger pulse. The range of programmable exposure time, the timing chart of the

exposure and the readout are shown below.
