12.11 Debouncer
The debouncer feature aids in discriminating between valid and invalid input signals and only lets
valid signals pass to the camera. The debouncer value specifies the minimum time that an input
signal must remain high or remain low in order to be considered a valid input signal.
Note that the debouncer delays a valid signal between its arrival at the camera and its transfer. The
duration of the delay will be determined by the debouncer value.
Figure 91 illustrates how the debouncer filters out invalid input signals, i.e. signals that are shorter
than the debouncer value. The diagram also illustrates how the debouncer delays a valid signal.
We recommend setting the debouncer value so that it is slightly greater than the
longest expected duration of an invalid signal.
Setting the debouncer to a value that is too short will result in accepting invalid
signals. Setting the debouncer to a value that is too long will result in rejecting valid
signals.
