Debounce filters

For the digital inputs, there are four debounce filters for each. These can be chosen and
configured for each signal independently. You have got the following filters at your
disposal:
 „Off" (without filter)
 „Stretch rising edge"
 „Stretch falling edge"
 „Stretch both edges"
 „Delay both edges"
For each filter, a debounce time has to be defined in µs. This debounce time can have a
value between [1µs...65535µs].
Off
The measured input signal is transferred without filtering.
„Stretch rising edge"
With the first rising edge, the input signal (red) switches to logical 1 and keeps this value
for the defined debounce time. Thereafter, the channel is transparent again and waits for
the next rising edge.
Figure 4:
„Stretch falling edge"
With the first falling edge, the output signal (green) switches to logical 0 and keeps this
value for the defined debounce time. Thereafter, the channel is transparent again and
waits for the next falling edge.
