4.8.4 External Trigger Exposure Mode (Ext Edge 1, 2)
In external trigger mode (Trigger Dual Edge Mode), exposure time is set through
external trigger signals CC1 and CC2. The line period is set by the period of external
trigger signal CC1, and the exposure start is set by the rising edge of external trigger
signal CC1. The range of programmable exposure time, and the timing chart of the
exposure and the readout are shown below.
