void EXTIX_Init(void)
{

  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0x03;
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; 
  NVIC_Init(&NVIC_InitStructure); 

    NVIC_InitStructure.NVIC_IRQChannel = EXTI8_IRQn;

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


  NVIC_InitStructure.NVIC_IRQChannel = EXTI3_IRQn;

  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0x00; 
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; 
  NVIC_Init(&NVIC_InitStructure);   
 
}

出现错误是：
..\HARDWARE\EXTI\exti.c(65): error:  #20: identifier "EXTI8_IRQn" is undefined
..\HARDWARE\EXTI\exti.c(78): error:  #20: identifier "EXTI13_IRQn" is undefined
..\HARDWARE\EXTI\exti.c - 2 Error(s), 0 Warning(s).
怎样修改才是对的，我都检查好几遍了，还是找不出为什么，各位大神帮帮忙吧，急急急

没有单独的中断8 和13    分别把他们改为 EXTI9_5_IRQn 和 EXTI15_10_IRQn 即可
