nvic_configuration_没有configuration选项_configuration什么意思

做stm32f103的低功耗实验，可以做到25uA,但设置了NVIC_Configuration(void)后，功耗变成30多mA，这是为什么，怎样解决？

void NVIC_Configuration(void)

{

NVIC_InitTypeDef NVIC_InitStructure;

NVIC_PriorityGroupConfig(NVIC_PriorityGroup_1);

NVIC_InitStructure.NVIC_IRQChannel =EXTI0_IRQn ;

NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 2;

NVIC_InitStructure.NVIC_IRQChannelSubPriority= 2;

NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;

NVIC_Init(&NVIC_InitStructure);

}

void NVIC_Config_Disable(void)

{

NVIC_InitTypeDef NVIC_InitStructure;

NVIC_PriorityGroupConfig(NVIC_PriorityGroup_1);

NVIC_InitStructure.NVIC_IRQChannel = EXTI0_IRQn ;

NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 2;

NVIC_InitStructure.NVIC_IRQChannelSubPriority = 2;

NVIC_InitStructure.NVIC_IRQChannelCmd = DISABLE;

NVIC_Init(&NVIC_InitStructure);

}

NVIC_Configuration();

RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR, ENABLE); //使能PWR外设时钟

 WR_EnterSTOPMode(PWR_Regulator_LowPower,PWR_STOPEntry_WFI);

主函数里执行这三句后功耗没降低。

NVIC_Configuration();

NVIC_Config_Disable();

RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR, ENABLE); //使能PWR外设时钟

 WR_EnterSTOPMode(PWR_Regulator_LowPower,PWR_STOPEntry_WFI);

主函数里执行这四句后功耗降低了。nvic_configuration
