10.2.2 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
a-synchronous. 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 figures 29 and 30.
To use this mode:
