This is missing your own SoB.

Now, I'd like to understand what you are actually trying to fix. What
is this 'ISR' exception? This isn't something the architecture
describes. Unless you are using CMOs on something that isn't memory or
for which you don't have a mapping, this should never generate an
exception.

Thanks,
