In fact, thanks a lot for finding this bug! I fixed ICR_ADRR before,
(it is correct in my sources and, I think in 2.0.38.1pre1), but I
didn't notice 4 leading 'f'-s instead of 5. Since I didn't use ICR
in my code it was OK.

Now I know why my friends were not able to configure edge interrupt!

Thanks again.
Vladimir
