4 Image Acquisition
start triggers are ignored. As soon as an acquisition start trigger has been received, the camera
waits for frame triggers. It can be a frame start trigger or a frame burst start trigger.
Depending which trigger - frame start or frame burst start - arrives first, the camera starts a
single frame or burst of frame acquisition.

4.3.3 Frame Burst End Trigger
The frame burst end trigger can be used to abort a current running burst capturing cycle. The
main property of this trigger is the trigger mode. It can be set to on or off:
Frame Burst End Trigger Mode = on The frame burst end trigger is processed only, when burst
acquisition cycle is active. Once this trigger has been received, it waits, until the current
frame has been processed and then aborts the burst cycle. The camera status goes to
"Frame Trigger Wait" again.
Frame Burst End Trigger Mode = off The frame burst end triggers are ignored.
The value "Acquisition Burst Frame Count" is ignored when the mode of the
frame burst end trigger is set to on. It means, when a burst capture has been
started, the camera captures frames until a frame burst end trigger arrives.
4.3.4 Frame Control Output Signals
The frame control block has the following output signals:
Frame Trigger Wait An asserted frame trigger wait indicates, that the frame control is waiting
for a frame start trigger (see Section 4.3.1), frame burst start trigger (see Section 4.3.2) or
an exposure start trigger (see Section 4.4.2).
Frame Active An asserted frame active signal indicates, that one or more frames are being
captured.
Frame Start
The frame start is an event, which is generated, when a new frame starts.
