3.4 Integrate Enabled Signal
The Integrate Enabled (IntEn) signal goes high when exposure begins and goes low when
exposure ends. This signal can be used as a flash trigger and is also useful when you are
operating a system where either the camera or the object being imaged is movable. For example,
assume that the camera is mounted on an arm mechanism and that the mechanism can move the
camera to view different portions of a product assembly. Typically, you do not want the camera to
move during exposure. In this case, you can monitor the IntEn signal to know when exposure is
taking place and thus know when to avoid moving the camera.
By default, the IntEn signal is assigned to physical output port 0 on the camera. See Section 2.5.2
for a description of the electrical characteristics of the camera’s physical output ports.
The assignment of the IntEn signal to a physical output port can be changed. See Section 6.7.11
for more information on changing the assignment of camera output signals to physical output
ports.

When you use the integrate enabled signal, be aware that there is a delay in the rise
and the fall of the signal in relation to the start and the end of exposure. See Figure
3-6 for details.
