Note
For the status display, the digital inputs only take into account the filter time of the
corresponding DI and not the filter time of the A/B/N signals of the fast counters (HSC).
For example, a static signal may be displayed when the DI has a configured input delay of
3.2 ms, even though a 100 kHz counter on these inputs still detects edge transitions.
