} while(0)

Configure the main internal regulator output voltage.

Parameters

__REGULATOR__

: Specifies the regulator output voltage to achieve a trade-off between performance and power consumption when the device does not operate at the maximum frequency (refer to the datasheet for more details). This parameter can be one of the following values: PWR_REGULATOR_VOLTAGE_SCALE0 : Regulator voltage output Scale 0 mode. 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.

Note

For STM32H74x and STM32H75x lines, configuring Voltage Scale 0 is only possible when Vcore is supplied from LDO (Low DropOut). The SYSCFG Clock must be enabled through __HAL_RCC_SYSCFG_CLK_ENABLE() macro before configuring Voltage Scale 0 using __HAL_PWR_VOLTAGESCALING_CONFIG(). Transition to Voltage Scale 0 is only possible when the system is already in Voltage Scale 1. Transition from Voltage Scale 0 is only possible to Voltage Scale 1 then once in Voltage Scale 1 it is possible to switch to another voltage scale. After each regulator voltage setting, wait on VOSRDY flag to be set using macro __HAL_PWR_GET_FLAG(). To enter low power mode , and if current regulator voltage is Voltage Scale 0 then first switch to Voltage Scale 1 before entering low power mode.

Return values

None.
