Okay got it and that would be my goto solution too but nevertheless it has to be possible to determine if a positive or negative edge triggered the interrupt right? I mean when using ANYEDGE. Because it is not possible to attach POSEDGE and NEGEDGE to the same pin. So the workaround would be to phys...
