You can enable a programmable debouncing filter on each PFI signal. When the filter is enabled, the chassis samples the inputs with a user-configured Filter Clock derived from the chassis timebase. This is used to determine whether a pulse is propagated to the rest of the circuit. However, the filter also introduces jitter onto the PFI signal.
