AT91SAM9260 USART PDC

Hi all,

I tried to use the uart with its pdc, using the ENDRX interrupt 
(at91sam9260-ek) - but I struggled! I always got the RXBUFF, and not as 
expected, the ENDRX interrupt even though both pdc channels where 
initialized.

Can anybody tell me, where I can found a basic example for IAR?

Thanks a lot for your help.
