各位大侠求助：
     使用STM32F205调试ADC问题，因为有多个通道，采用定时器3溢出事件触发ADC采样，多个通道，使用DMA方式进行数据传输，使用ST-link调试，发现能进DMA中断，但是既不是全中断，也不是半中断（配置DMA开了全中断和半中断），求解。谢谢。

    附上源码：

最怪异的是中断函数，在两个if(DMA_GetITStatus(xxx))处打断点能进，DMA_ClearFlag ( DMA2_Stream0,DMA_FLAG_TCIF0);和DMA_ClearFlag(DMA2_Stream0,DMA_FLAG_HTIF0);却不能执行到但却不是这两个中断引发的，求解？
void DMA2_Stream0_IRQHandler(void)
{
    if(DMA_GetITStatus(DMA2_Stream0,DMA_FLAG_TCIF0) != RESET )//全中断
    {
        DMA_ClearFlag ( DMA2_Stream0,DMA_FLAG_TCIF0);
           //执行不到
    }
    else if(DMA_GetITStatus(DMA2_Stream0,DMA_FLAG_HTIF0) != RESET )//半中断  
    {
        DMA_ClearFlag(DMA2_Stream0,DMA_FLAG_HTIF0);
         //执行不到
    }
    else
    {
        //从这执行退出了
        DMA_ClearFlag(DMA2_Stream0, DMA_FLAG_HTIF0 | DMA_FLAG_TCIF0| DMA_FLAG_DMEIF0);
        return;
    }
