You have way to much faith in the hardware. Promise is especially known
for not keeping to the spec. I wouldn't trust the interrupt bit to be
valid unless a dma is actually active, i.e. that
has actually been written.
I've actually had a manufacturer tell me that they don't worry about the
spec, just making things work with Windows.
