Hello ST Community,
I am using RTC backup register of STM32F746ZG for saving some accumulating data.
So i'm afraid of situation when i start write operation and in the same time the VDD power is disabled.
Couldn't find any information about this, so i assume, the only way to guarantee data consistency will be duplicating it?

The BOR should protect you from undefined behavior, although it may kick in midway through updating the registers, so half may be updated while the other half are not.

Thanks for you answer!
I can deal with updating only half (actually I'm using only one register for that kind of data).
