Looking at the 3664 Spec more closely, use of the BASIC Atom Pro Flash in a
run time environment requires use of the User Program Mode.  This requires
running your code out of RAM while the Flash is programmed.  Since the BASIC
ATOM compiler does not appear to support this, it looks like you could never
use the internal Flash memory for run time storage.  This applies to PSIM or
any new design.
