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.
