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
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 28 and 29.
To use this mode:

1) In case of a-synchronous mode, the exposure time should be added to the above
table.
2) In order to keep the minimum trigger interval in partial scan mode, a exposure time
should be set within a number of normal read out line(511L). If it is exceeded, the
minimum trigger interval is longer by (exposure time – 511L).
