AVR external interrupt

[saurabh17g]

I have set up external interrupt for ATmega32 and my program executing external interrupt service routine. The question is during the execution of the routine, if external interrupt hits the pin again, does the routine continues to execute or the routine is stopped and again begun. I am using Codevision AVR for programming.

While executing the external interrupt if another interrupt occurs in the same pin, it will be ignored. If you want to sense the second interrupt also, then process can be brought out of interrupt routine.
