  • PWR_FLAG_WU: Wake Up flag
  • PWR_FLAG_SB: StandBy flag

void PWR_EnterSTANDBYMode ( void  )

Enters STANDBY mode.

Note
In Standby mode, all I/O pins are high impedance except for:
  • Reset pad (still available)
  • RTC_AF1 pin (PC13) if configured for tamper, time-stamp, RTC Alarm out, or RTC clock calibration out.

void PWR_EnterSTOPMode ( uint32_t  PWR_Regulator,

Enters STOP mode.

Note
In Stop mode, all I/O pins keep the same state as in Run mode.
When exiting Stop mode by issuing an interrupt or a wakeup event, the HSI RC oscillator is selected as system clock.
When the voltage regulator operates in low power mode, an additional startup delay is incurred when waking up from Stop mode. By keeping the internal regulator ON during Stop mode, the consumption is higher although the startup time is reduced.

  • PWR_Regulator_ON: STOP mode with regulator ON
  • PWR_Regulator_LowPower: STOP mode with regulator in low power mode

  • PWR_STOPEntry_WFI: enter STOP mode with WFI instruction
  • PWR_STOPEntry_WFE: enter STOP mode with WFE instruction
Return values
None
Parameters
PWR_Regulatorspecifies the regulator state in STOP mode. This parameter can be one of the following values:
  • PWR_Regulator_ON: STOP mode with regulator ON
  • PWR_Regulator_LowPower: STOP mode with regulator in low power mode
PWR_STOPEntryspecifies if STOP mode in entered with WFI or WFE instruction. This parameter can be one of the following values:
  • PWR_STOPEntry_WFI: enter STOP mode with WFI instruction
  • PWR_STOPEntry_WFE: enter STOP mode with WFE instruction
Return values
None

FlagStatus PWR_GetFlagStatus ( uint32_t  PWR_FLAG)

Checks whether the specified PWR flag is set or not.

Parameters
PWR_FLAGspecifies the flag to check. This parameter can be one of the following values:
  • 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 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.
Return values
Thenew state of PWR_FLAG (SET or RESET).
Parameters
PWR_FLAGspecifies the flag to check. This parameter can be one of the following values:
  • PWR_FLAG_WU: Wake Up flag
  • PWR_FLAG_SB: StandBy flag
  • PWR_FLAG_PVDO: PVD Output

  • 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.
  • PWR_FLAG_VREFINTRDY: Internal Voltage Reference Ready flag. This flag indicates the state of the internal voltage reference, VREFINT.
