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