AT91SAM7S: nested interrupt function

Peter Brandon

Hi,

I want to add a function handling nested interrupts for the controller. Could you tell me the right position to add this function?

startup-file:

Undef_Handler   B       Undef_Handler
SWI_Handler     B       SWI_Handler
PAbt_Handler    B       PAbt_Handler
DAbt_Handler    B       DAbt_Handler
;IRQ_Handler     B       IRQ_Handler
IRQ_Handler     B       irq_fnct
FIQ_Handler     B       FIQ_Handler

irq_fnct

   //do some stuff - nested interrupt

I've add one breakpoint to the irq_fnct but it seems that the programm will not reach this part if a interupt occur.

I'm working with the atmel controller AT91SAM7S.

best regards
Peter
