/** @brief  Check PWR flag is set or not.

  *           This parameter can be one of the following values:
  *            @arg PWR_FLAG_WU: Wake Up flag. This flag indicates that a wakeup event
  *                  was received from the WKUP pin or from the RTC alarm (Alarm A),
  *                  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. 
  *                  Warning: this Flag is not available on STM32F030x8 products
  *            @arg PWR_FLAG_VREFINTRDY: This flag indicates that the internal reference
  *                  voltage VREFINT is ready.
  *                  Warning: this Flag is not available on STM32F030x8 products
