Error on PITn

I try to use PITn (periodic interrupt timer) for one of my application. I work with k60 kinetis with IAR IDE.


I program rthe PIT0 to generate a interrupt every N secondes but when I try to do the same think with the PIT1 I get an error.


As soon as I try to modify one of the register of PIT1 (PIT_LDVAL1 for example) the CPU generate an interrupt (vector 3 :Hard Fault).



I don't really understand the reason of that error...


Can someone explain me the reason of this? Or give me some advice about it?



Best regard.
