咨询有关GPIO的中断

大家好：

我用例程包“STK_C6657.7z”里的GPIO程序做测试，6657的评估板上输出如下：

Initialize DSP main clock = 100.00MHz/1x10 = 1000MHz
GPIO interrupt event flag on CorePac INTC = 0x1

Test complete.

在评估板上试过了 在自己的板子上试过了 输出一样的 难道软件有问题？？？？

    在论坛搜了一下 91号事件对应GPIO0/1， 在6657上， core 0的91号事件对应GPIO0， core 1的91号事件对应GPIO1。

    GPIO IN_DATA= 0x2                                                  //这里没有进中断

    GPIO IN_DATA= 0x0                                                  //这里没有进中断

    这个理解了。


    GPIO interrupt event flag on CorePac INTC = 0x0  //进中断  但INTC不对 应该是0x04才对？？？
    GPIO IN_DATA= 0x4

    GPIO interrupt event flag on CorePac INTC = 0x0 /进中断  但INTC不对 应该是0x04才对？？？
    GPIO IN_DATA= 0x0

    GPIO interrupt event flag on CorePac INTC = 0x0 /进中断  但INTC不对 应该是0x08才对？？？
    GPIO IN_DATA= 0x8

    GPIO interrupt event flag on CorePac INTC = 0x0 /进中断  但INTC不对 应该是0x08才对？？？
    GPIO IN_DATA= 0x0

    这个怎么理解？？？

    进中断后，event清除掉了

    什么意思 讲的再详细些 其它的没清掉啊？

    我再看看 谢了！

    printf("GPIO interrupt event flag on CorePac INTC = 0x%x\n",

    ((eventFlag&(~(1<<(CSL_GEM_GPINTN-64))))>>(10))|((eventFlag>>(CSL_GEM_GPINTN-64))<<DNUM));


    判断有BUG
