Hello all, I have seen an old post a while ago discussing an interesting problem but I just don't seem to be able to find it: Somebody described an interesting experiment that demonstrated that setting IEN to 0 does not shut down interrupt immediately but after a couple of clock cycles. If I remember correctly, he suggested solving the problem like this:
_atomic(0) ; IEN = 0 ;
Is there indeed a reason to be worried given the prefetch pipeline?
Thanks in advance, Tamir Michael
