4.8.2 External Trigger (Timed) Exposure Mode
External trigger (Timed) exposure mode is the mode when the external trigger
enable is enabled (Triggermode: on) and the exposure mode is Timed (Exposure
Mode: Timed).
The line cycle is set by the cycle of the external trigger, and exposure start is set by
the rising edge of the external trigger. Set the exposure time to the programmable
exposure time (ExposureTime). The settable line cycle and programmable exposure
time are as follows.

The programmable exposure time is 0.200us steps.
The relationship between programmable exposure time (us) and line period (us) is as follows.
