##### FLASH Power Down configuration functions #####
===============================================================================
[..]
(+) By setting the FPDS bit in the PWR_CR register by using the
PWR_FlashPowerDownCmd() function, the Flash memory also enters power
down mode when the device enters Stop mode. When the Flash memory
is in power down mode, an additional startup delay is incurred when
waking up from Stop mode.

void PWR_ClearFlag |
( |
uint32_t |
PWR_FLAG | ) |
|
Clears the PWR's pending flags.
- Parameters
-

- PWR_FLAG_WU: Wake Up flag
- PWR_FLAG_SB: StandBy flag
|
- Return values
-
Definition at line 514 of file stm32f30x_pwr.c.
Enables or disables the Flash Power Down in STOP mode.
- Parameters
-
NewState | new state of the Flash power mode. This parameter can be: ENABLE or DISABLE. |
- Return values
-
Definition at line 378 of file stm32f4xx_pwr.c.
Checks whether the specified PWR flag is set or not.
- Parameters
-
PWR_FLAG | specifies 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.
- 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.

- Return values
-
The | new state of PWR_FLAG (SET or RESET). |
