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.
Frame End The frame end is an event, which is generated, when a frame is finished.
Frame Burst Start The frame burst start is an event, which is generated, when a new burst of
frame starts.
Frame Burst End
The frame burst end is an event, which is generated, when a burst of frame is
finished.
Frame Trigger The frame trigger is an event, which is generated, when a frame is started by a
frame start trigger (see Section 4.3.1), by a frame burst start trigger (see Section 4.3.2) or
by an exposure start trigger (see Section 4.4.2).
Frame trigger wait and frame active status signal are routed to the I/O control block and can
there be selected for output on the physical output line or on one of the available leds. Frame
start, frame end and frame trigger event can be used to trigger or to control other function in
the camera, like counter and timer.
