5.9.2 External Trigger Exposure Mode (Trigger Edge)
In external trigger exposure mode (Trigger Edge), the exposure time is determined
by setting the control register, and the line period is determined by the external
trigger period. Each exposure starts with the 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.
