STM32 BBRAM are 32-bit registers which can be used for storing user |
|
application data. They are implemented in the backup domain that remains |
|
powered-on by VBAT when the VDD power is switched off. They are not reset |
|
by system reset or when the device wakes up from Standby mode. They are |
|
reset by a backup domain reset.
