This flag indicates that a wakeup event was received from the WKUP pin or from the RTC alarm (Alarm A or Alarm B), RTC Tamper event, RTC TimeStamp event or RTC Wakeup. An additional wakeup event is detected if the WKUP pin is enabled (by setting the EWUP bit) when the WKUP pin level is already high. PWR_FLAG_SB: StandBy flag. This flag indicates that the system was resumed from StandBy mode. PWR_FLAG_PVDO: PVD Output. This flag is valid only if PVD is enabled by the PWR_PVDCmd() 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. 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. PWR_FLAG_VOSRDY: This flag indicates that the Regulator voltage scaling output selection is ready.
