It's not unheard of, though test it thoroughly.  Even if a peripheral is
"off" or disabled it can cause some registers to change (like interrupt
flags which change no matter what the state of the enable). I'd make sure
it was a 'configuration' type register rather than a 'flag' register for a
first pass.
