求教STM32F103进入STOP模式后用外部中断唤醒的问题

void EXTI0_IRQHandler(void)
{

RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR | RCC_APB1Periph_BKP, ENABLE);
if(EXTI_GetITStatus(EXTI_Line0) != RESET) //检查指定的EXTI0线路触发请求发生与否
{

EXTI_ClearITPendingBit(EXTI_Line0); //清除EXTI0线路挂起位
EXTI_ClearFlag(EXTI_Line0); //清楚EXTI0线路挂起标志位
if(STOP_MODEL())
{
PWR_EnterSTOPMode(PWR_Regulator_LowPower,PWR_STOPEntry_WFI);
}
}
}

void EXTI1_IRQHandler(void)
{

ErrorStatus HSEStartUpStatus;
RCC_HSEConfig(RCC_HSE_ON);

    /* Wait till HSE is ready */
HSEStartUpStatus = RCC_WaitForHSEStartUp();

if(HSEStartUpStatus == SUCCESS)
{
/* Select HSE as system clock source */
     RCC_SYSCLKConfig(RCC_SYSCLKSource_HSE);
}
if(EXTI_GetITStatus(EXTI_Line1) != RESET) //检查指定的EXTI1线路触发请求发生与否
{
EXTI_ClearITPendingBit(EXTI_Line1); //清除EXTI1线路挂起位
EXTI_ClearFlag(EXTI_Line1); //清楚EXTI1线路挂起标志位
}
}
通过中断0使CPU进入STOP模式，想通过中断1来唤醒，但是无法唤醒
中断配置如下
GPIO_InitTypeDef GPIO_InitStructure;
   EXTI_InitTypeDef EXTI_InitStructure;
   NVIC_InitTypeDef NVIC_InitStructure;

RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB|RCC_APB2Periph_GPIOA|RCC_APB2Periph_AFIO,ENABLE);

//init GPIOB.0     下拉输入
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPD;

GPIO_Init(GPIOB, &GPIO_InitStructure);

//GPIOB.0
   GPIO_EXTILineConfig(GPIO_PortSourceGPIOB,GPIO_PinSource0);

   EXTI_InitStructure.EXTI_Line=EXTI_Line0;
EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt;
EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Falling;
EXTI_InitStructure.EXTI_LineCmd = ENABLE;
EXTI_Init(&EXTI_InitStructure);

NVIC_InitStructure.NVIC_IRQChannel = EXTI0_IRQn;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0x02;
NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0x02;
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
NVIC_Init(&NVIC_InitStructure);

//init GPIOA.1     下拉输入
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPD;
GPIO_Init(GPIOA, &GPIO_InitStructure);

    //GPIOA.1
GPIO_EXTILineConfig(GPIO_PortSourceGPIOA,GPIO_PinSource1);

EXTI_InitStructure.EXTI_Line=EXTI_Line1;
EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt;
EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Rising;
EXTI_InitStructure.EXTI_LineCmd = ENABLE;
EXTI_Init(&EXTI_InitStructure);

NVIC_InitStructure.NVIC_IRQChannel = EXTI1_IRQn;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0x03;
NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0x02;
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
NVIC_Init(&NVIC_InitStructure);
新手没有积分，还希望大侠们指点。
