External Trigger Exposure Mode (Trigger Edge)

In External Trigger Exposure Mode (Trigger Edge),exposure time is set through

the registers, the scan period is set by the period of the external trigger signal

(Line Trigger), and the exposure start is set by the rising edge of the external

trigger signal. The possible range of exposure time, and the relationship between

the timing of exposure and readout is explained below.

As with free run exposure mode, the minimum scan cycle changes depending on

the image format.
