#define __HAL_PWR_CLEAR_ODRUDR_FLAG

#define __HAL_PWR_GET_ODRUDR_FLAG

(

__FLAG__

)

((PWR->CSR & (__FLAG__)) == (__FLAG__))

Check PWR flag is set or not.

Note:

These macros can be used only for STM32F42xx/STM3243xx devices.

Parameters:

__FLAG__

specifies the flag to check. This parameter can be one of the following values: PWR_FLAG_ODRDY: This flag indicates that the Over-drive mode is ready PWR_FLAG_ODSWRDY: This flag indicates that the Over-drive mode switching is ready PWR_FLAG_UDRDY: This flag indicates that the Under-drive mode is enabled in Stop mode

Return values:

The	new state of __FLAG__ (TRUE or FALSE).

#define __HAL_PWR_UNDERDRIVE_ENABLE

(

)

(PWR->CR |= (uint32_t)PWR_CR_UDEN)

Macros to enable or disable the Under drive mode.

Note:

This mode is enabled only with STOP low power mode. In this mode, the 1.2V domain is preserved in reduced leakage mode. This mode is only available when the main regulator or the low power regulator is in low voltage mode.

If the Under-drive mode was enabled, it is automatically disabled after exiting Stop mode. When the voltage regulator operates in Under-drive mode, an additional startup delay is induced when waking up from Stop mode.

macros configure the main internal regulator output voltage.

Parameters:

__REGULATOR__

specifies the regulator output voltage to achieve a tradeoff between performance and power consumption when the device does not operate at the maximum frequency (refer to the datasheets for more details). This parameter can be one of the following values: PWR_REGULATOR_VOLTAGE_SCALE1: Regulator voltage output Scale 1 mode PWR_REGULATOR_VOLTAGE_SCALE2: Regulator voltage output Scale 2 mode PWR_REGULATOR_VOLTAGE_SCALE3: Regulator voltage output Scale 3 mode

Return values:

None
