* 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.
* @arg PWR_FLAG_SB: StandBy flag. This flag indicates that the system was
* resumed from StandBy mode.
* @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_VREFINTRDY: Internal voltage reference (VREFINT) ready flag.
* This bit indicates the state of the internal voltage reference, VREFINT.
* @arg PWR_FLAG_VOS: Voltage Scaling select flag. A delay is required for
* the internal regulator to be ready after the voltage range is changed.
* The VOSF bit indicates that the regulator has reached the voltage level
* defined with bits VOS of PWR_CR register.
* @arg PWR_FLAG_REGLP: Regulator LP flag. When the MCU exits from Low power run
* mode, this bit stays at 1 until the regulator is ready in main mode.
* A polling on this bit is recommended to wait for the regulator main mode.
* This bit is reset by hardware when the regulator is ready.
