XC16X: No extern interrupt on Port9.2

Rainer Birkner

Hi, I use an XC164CM controller (on a Infineon Evalboard). My problem is, thats not possible to start an extern interrupt (EX4IN) on Portpin P9.2.
The register values are correct for the simulation with µVision3. Probably I have a hardware problem.
The positive trigger edge is from a 74LS00. But the controller can't detect the edge and no interrupt is started.
Some ideas?
Kindly regards
Rainer
