Hi, I am using STR9FAW44, and I get an external interrupt from WIU line 18(GPIO P6.2 pin). When CPU gets an interrupt from this pin it halts, it does not give any reaction. When I debug, it goes into interrupt routine, but when it returns from the intterrupt routine it jumps a memory address where includes some absurd things. Then it does noting.
What may be the cause of this problem?
