4.8.2 External Trigger Exposure Mode

In external trigger exposure mode, the line period and the exposure time is determined

by the setting made through the external trigger pulse (CC1) cycle. Each exposure starts

with the rising edge is determined by the time from rising edge to rising edge of the

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

exposure and the readout are shown below.
