stm32f103zet6 RTC能从待机模式唤醒不能从停止模式唤醒?
代码：

int main(void)
{
  /* USER CODE BEGIN 1 */
  /* USER CODE END 1 */

  /* MCU Configuration--------------------------------------------------------*/

  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();

  /* USER CODE BEGIN Init */

  /* USER CODE END Init */

  /* Configure the system clock */
  SystemClock_Config();

  /* USER CODE BEGIN SysInit */
  RtcClock_Config();
  MY_RTC_Init();
  /* USER CODE END SysInit */

  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_USART1_UART_Init();

  /* USER CODE BEGIN 2 */

  RTC_Alarm_Set(2019,1,14,16,55,00);
  RTC_Alarm_IT_Enable(&hrtc);

  printf("Start! ");

  /* USER CODE END 2 */

  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {
HAL_Delay(500);
HAL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin); //灭
HAL_Delay(500);
HAL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin); //亮
HAL_Delay(500);
HAL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin); //灭
HAL_Delay(500);
HAL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin); //亮
HAL_Delay(500);

//SleepMode();
StopMode_IT();
//StandbyMode();

RTC_Alarm_IT_Enable(&hrtc);

/* 检测系统是否是从待机模式启动的 */
if (__HAL_PWR_GET_FLAG(PWR_FLAG_SB) != RESET)
{
   printf("待机唤醒复位 ");
   /* 清除待机标志位 */
   __HAL_PWR_CLEAR_FLAG(PWR_FLAG_SB);
}
else
{
   printf("系统是上电启动 ");
}

RTC_Get();
printf("%2d年%2d月%2d日 ------ ", calendar.w_year, calendar.w_month, calendar.w_date);
printf("%2d点%2d分%2d秒 ------ ", calendar.hour, calendar.min, calendar.sec);
printf("星期%d ", calendar.week);

//StandbyMode();

// HAL_GPIO_TogglePin(SIGNAL_GPIO_Port, SIGNAL_Pin);

/* USER CODE END WHILE */

/* USER CODE BEGIN 3 */
  }
  /* USER CODE END 3 */
}

HAL_StatusTypeDef RTC_Alarm_IT_Enable(RTC_HandleTypeDef *hrtc)
{
  /* Process Locked */
  __HAL_LOCK(hrtc);

  hrtc->State = HAL_RTC_STATE_BUSY;

  __HAL_RTC_ALARM_EXTI_CLEAR_FLAG();

  /* Clear flag alarm A */
  __HAL_RTC_ALARM_CLEAR_FLAG(hrtc, RTC_FLAG_ALRAF);

  /* Configure the Alarm interrupt */
  __HAL_RTC_ALARM_ENABLE_IT(hrtc,RTC_IT_ALRA);

  /* RTC Alarm Interrupt Configuration: EXTI configuration */
  __HAL_RTC_ALARM_EXTI_ENABLE_IT();

  __HAL_RTC_ALARM_EXTI_ENABLE_RISING_EDGE();

  hrtc->State = HAL_RTC_STATE_READY;

  __HAL_UNLOCK(hrtc);

  return HAL_OK;
}
怀疑是EXTI17没配置好，不知道是哪出问题？
