Hello,

I would like some confirmation on the Due regarding the Digital I/O.  I know that the AVR boards allow the analog pins to be configured as digital IO, but how about this Due?  I am sure it can, I would just like some confirmation.

Also,

If the former is true, can you attachInterrupt() on these pins?

Are there any concerns regarding the use of analog pins as digital IO and external, such as speed?

Thanks,
Daniel
