• Active high / Active low (only for physical inputs)
Setting whether the input is active at high or low voltage level. The logic uses the active input state for further processing and
not the voltage level.

• Validation
Requires an input signal to be consistent for the defined period of time before it is acknowledged as input. The validation causes
a small delay, but avoids unwanted switching operations due to short peaks (see figure 20).
• Debounce
When a change of state is detected, the input signal is immediately stabilised or debounced for the set period of time (see figure 20).
