problem with timer/counter of AT91SAM7x

Dear All;
I’m using the timer/counter of AT91SAM7x and its interrupt is enabled. But I encountered a problem. When the instructions in main() are executing, the timer/counter interrupt does not work. I mean the instructions in the ISR() do not execute until the instructions in the main() are executing. It seems that the priority of timer/counter interrupt is less than normal instructions. Is it a normal phenomenon in AT91SAM7x?
Best Regards
