FWIW, I see things the same as Phil. Either unprotect the register before 
bumping it, or don't use the feature, or potentially ignore the warning.

Sure, but...so? You'd explicitly unprotect, change, reprotect. That's the whole 
point. (Or not protect at all; this is optional, after all.)

Seriously, not picking a fight, just don't understand whether you're saying 
"This doesn't work because" or "Note that in cases like this, there'd be some 
tinkering"?
