It's not the CPU, it's more the MMU which can help in finding changed

AFAIK, the MMU can not work in byte addresses but just with much bigger
blocks of data. So it does not seem to help with finding a write access
to a dedicated variable.
Moreover the MMU programming and interrupts will be consumed by the OS
and a user space program can't even see it.
