Arguments

Argument

Description

__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: @arg PWR_REGULATOR_VOLTAGE_SCALE1: Regulator voltage output Scale 1 mode @arg PWR_REGULATOR_VOLTAGE_SCALE2: Regulator voltage output Scale 2 mode @arg PWR_REGULATOR_VOLTAGE_SCALE3: Regulator voltage output Scale 3 mode

Return value

None
