Rather than do this, I would prefer you use a function local variable
and load the global immr into it. You should also get into the habit
of using barrier operations between such I/O accesses that must be
properly ordered. The global volatile declaration isn't sufficient
to enforce ordered operations. You just got lucky this time.
Thanks.
