  *                  RTC Tamper event, RTC TimeStamp event or RTC Wakeup.

  *                  (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

  *            @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.
