Re: Illegal address in DataPort

I think you can certainly access these locations from a native method, its
just that the DataPort class in Java will return an illegal address
exception. That's my understanding anyway. Just like you can write native
methods to program the expansion flash on a Tini390, but can't access it
with a DataPort.
