Problem with interrupts in a KL17Z256 processor.

Dear all.

 

I am trying to configure different interrupts on a KL 17Z256 processor ( KSDK1.0.0 and Kinetis 2.0 IDE.) but run into problems when several interrupts arrive within a short time frame. My main loop then simply get stuck.

 

Hence I have some questions.

1) Are nestled interrupts enabled as default, that is, will my ISR routine get interrupted for other interrupts of higher prio?

2) Do I need to run PORT_HAL_ClearPinIntFlag after entering the ISR, or is this handled by itself. I have seen many different ideas about this on the internet, and in ARMs documention they state that the flag is cleared after entering the ISR.

 

Kind Regards
