What is the type of functionality you're trying to achieve? Please share more details on it.
i try to explain it more in detail.
I have one pin (pinA) configured as Interrupt-Input.
when i detect a falling edge, i want to create a pulse on another Pin (PinB).
pinA : ---------------|_________|------------
The length of the pulse should be configurable (< 1 msec).
It is not possible to do this with a timer and simple gpio(which i have tried),
so maybe it is possible with a cpmplex gpio.
It does seem possible at first look. Can you please create a tech support case (MyAccount->MyCases) for this so that one of our engineers can look at the kind of flexibility you're looking at and the method that'll be needed to implement it.
