请教一个中断配置的问题？

homo

我的中断配置代码如下，想问一下，为什么进入不了中断响应函数呢？谢谢
void EXTILine_Config(void)
{
NVIC_InitTypeDef   NVIC_InitStructure;
EXTI_InitTypeDef   EXTI_InitStructure;

GPIO_InitTypeDef  GPIO_InitStructure;

  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0|GPIO_Pin_1|GPIO_Pin_9|GPIO_Pin_6; 
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;//100M
  GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP;
  GPIO_Init(GPIOC, &GPIO_InitStructure);

 
RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);

 
SYSCFG_EXTILineConfig(EXTI_PortSourceGPIOC, EXTI_PinSource0|EXTI_PinSource1|EXTI_PinSource9|EXTI_PinSource6)；

  EXTI_Init(&EXTI_InitStructure);


  EXTI_InitStructure.EXTI_Line = EXTI_Line9;
  EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt;
  EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Rising; 
  EXTI_InitStructure.EXTI_LineCmd = ENABLE;

还有一个问题，就是在PF8端口上加电压，竟然进入了EXTI9_5_IRQHandler中断响应函数，奇怪啊！

八度空间

1、EXTI_InitStructure.EXTI_Line = EXTI_Line0|EXTI_Line1;

2、NVIC_InitStructure.NVIC_IRQChannel = EXTI0_IRQn|EXTI1_IRQn;

3、EXTI9_5_IRQHandler

以上问题：
1和2、好像没有这样的写法吧，记得都是分开来配置的
3、PIN8管脚的中断就是在这里的，看中断服务函数名称就知道了，这个服务函数是pin5 ~ pin9管脚通用的一个中断服务函数

SYSCFG_EXTILineConfig(EXTI_PortSourceGPIOC, EXTI_PinSource0|EXTI_PinSource1|EXTI_PinSource9|EXTI_PinSource6)；这段语句是将PC9，PC6连接到中断线上，没有配置PF8啊？

正点原子

好好学习下我们的例程先吧。
