By OR logic pulses and bounces can generate an interrupt.
The following parameters are set in the figure below:
1
st
condition: The channels 0/4 and 1/5 react to rising edges (Modus_1 = 11).
2
nd
condition: The channels 0/4 and 1/5 react to falling edges (Modus_2 = 11).

* 10:
Interrupt source:
the 2
nd
input (channel 1/5) has generated an interrupt.
** 01:
Interrupt source:
the 1
st
input (channel 0/4) has generated an interrupt.
