| This option enables the BBRAM driver for STM32 family of |
| processors. |

| 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. |
