
Then choose the corresponding interrupt contact from the drop down list of External event.

The setting value for hardware filter time is smaller than IN input duty on time as shown below:

The input range for hardawre filter is from 0 to 50,000,000, unit as 0.01
μ
s

The relation between filter frequency and filter time:
Filter frequency*
1
(Hz): Filter frequency= 1 / (2*t); t is the filter time setting value (unit:
0.01μ
s). When input
frequency is higher than the filter frequency range, signals are filtered.
The function focuses on the X input point used in DFB_Capture, DFB_Hcnt, DFB_HTmr, DFB_Compare and
IO interrupt.
