Pre-select Trigger Mode
An external trigger pulse initiates the capture, and the exposure time (accumulation time) is
defined by the SH or PE commands.
The resulting video signal will start to be read out after the selected shutter time.
For timing details, refer to fig. 8 through fig. 13 and fig. 14 & 15.
To use this mode:

Input:
Important notes on using this mode
1. The minimum trigger interval >1 LVAL.
2. Depending on the timing of the leading edge of the trigger pulse in relationship to
FVAL, accumulation will be synchronous or a-synchronous in relationship to LVAL. See
chapter 6.1.5 for details.
