MPC5744p SIUL2 External Interrupt 0

SIUL2 External Interrupt 0 trigerring:

does someone have an application example which uses the "SIUL2 External Interrupt 0" ?

i configured the MPC5744p to use the "SIUL2 External Interrupt 0" as an external input, and mapped the "ISRs 243" to my ISR243_Function(), and there are 2 huge problems:

1 => The interrupt never pens ! (Even the IVOR4 is never called !).

2=> Instead of that, i have an unexplained Reset (hapenning when setting the electrical line to HIGH state), and which makes my PC point to illegal memory area !!!

Your hel please !

Thank you so much.

Salah.
