Camera interfaces
The following diagram illustrates the dependencies of the various output signals.

Note that the polarity of the signals can be changed.
Firing a new trigger while IntEna is still active can result in image corruption due to double
exposure occurring.
Note that trigger delay in fact delays the image capture whereas the IntEna_Delay only
delays the leading edge of the IntEna output signal but does not delay the image capture.
As mentioned before, it is possible to set the outputs by software. Doing so, the achievable
maximum frequency is strongly dependent on individual software capabilities. As a rule of
thumb, the camera itself will limit the toggle frequency to not more than 700 Hz.
