Hi all,


I've noticed that in every example and CubeMX generated code the backup domain access bit is set and never reset. It is as if once the application starts the access is allowed and never restricted again, so it make s me wonder what's the point?

In my code I enable access when needed (e.g. setting RTC time and date) and disable the access once I'm done, seems more appropriate to me. My question is if what I do is necassary or should I just eave the enable bit set an forget about it?
