10.2.2 Edge Pre-Select trigger mode
An external trigger pulse initiates the capture, and the exposure time (accumulation time) is the
fixed shutter speed set by registers. The accumulation can be LVAL synchronous or LVAL
asynchronous. The resulting video signal will start to be read out after the selected shutter time.
For timing details, refer to fig. 19. through fig. 24 and fig.28 and 29.
To use this mode:
