rc, GPIO, gp, IO, pi, sleep

请问N32WB03 在进入sleep之前，配置了外部中断，但是sleep了之后外部中断唤不醒，进不去对应的中断服务函数是什么原因，
代码：
{
LEDInit(GPIOB,GPIO_PIN_2);
KeyInputExtiInit(KEY_INPUT_PORT, KEY_INPUT_PIN);

/* Enable PWR Clock */
      RCC_EnableAPB1PeriphClk(RCC_APB1_PERIPH_PWR, ENABLE);
      //enter sleep
      PWR_EnterSLEEPMode(PWR_SLEEPENTRY_WFI);
}

void KeyInputExtiInit(GPIO_Module* GPIOx, uint16_t Pin)
{
GPIO_InitType GPIO_InitStructure;
EXTI_InitType EXTI_InitStructure;
NVIC_InitType NVIC_InitStructure;

/* Check the parameters */
assert_param(IS_GPIO_ALL_PERIPH(GPIOx));

/* Enable the GPIO Clock */
if (GPIOx == GPIOA)
{
      RCC_EnableAPB2PeriphClk(RCC_APB2_PERIPH_GPIOA | RCC_APB2_PERIPH_AFIO, ENABLE);
}
else if (GPIOx == GPIOB)
{
      RCC_EnableAPB2PeriphClk(RCC_APB2_PERIPH_GPIOB /*| RCC_APB2_PERIPH_AFIO*/, ENABLE);
}
else
{
      return;
}

/*Configure the GPIO pin as input floating*/
if (Pin <= GPIO_PIN_ALL)
{
      GPIO_InitStruct(&GPIO_InitStructure);
      GPIO_InitStructure.Pin       = Pin;
GPIO_InitStructure.GPIO_Mode = GPIO_MODE_INPUT;
      GPIO_InitStructure.GPIO_Pull = GPIO_NO_PULL;
      GPIO_InitPeripheral(GPIOx, &GPIO_InitStructure);
}

/*Configure key EXTI Line to key input Pin*/
GPIO_ConfigEXTILine(KEY_INPUT_PORT_SOURCE, KEY_INPUT_PIN_SOURCE);

/*Configure key EXTI line*/
EXTI_InitStructure.EXTI_Line = KEY_INPUT_EXTI_LINE;
EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt;
EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Rising; // EXTI_Trigger_Rising;
EXTI_InitStructure.EXTI_LineCmd = ENABLE;
EXTI_InitPeripheral(&EXTI_InitStructure);

/*Set key input interrupt priority*/
NVIC_InitStructure.NVIC_IRQChannel                = KEY_INPUT_IRQn;
NVIC_InitStructure.NVIC_IRQChannelPriority          = 1;
NVIC_InitStructure.NVIC_IRQChannelCmd             = ENABLE;
NVIC_Init(&NVIC_InitStructure);
}
