* An additional wakeup event is detected if the WKUP pin is enabled

* @arg PWR_FLAG_SB: StandBy flag. This flag indicates that the system was

* @arg PWR_FLAG_PVDO: PVD Output. This flag is valid only if PVD is enabled
* by the HAL_PWR_EnablePVD() function. The PVD is stopped by Standby mode
* For this reason, this bit is equal to 0 after Standby or reset
* until the PVDE bit is set.
* @arg PWR_FLAG_BRR: Backup regulator ready flag. This bit is not reset
* when the device wakes up from Standby mode or by a system reset
* or power reset.

* scaling output selection is ready.
