更改通知中断设置问题

你好，PIC Guur'SI正在尝试改变通知中断工作在PIC32 MX470F512L设备上，我有点问题。我不认为ISR被正确调用。程序功能很简单：1）在端口D配置PIN 0和1，输出引脚1高2）I配置端口D上的PIN 6作为输入，然后将其配置为接收中断。步骤2，从我所理解的要求，我改变总共7个寄存器（tiS，CNPU，CN）。CON，CNEN，IFS1，IPC8和IEC，我已经做了。但是，我不认为ISR实际上是被调用的。为了延迟，我做了一个Debug函数（dB（））。谢谢你的时间！包含：“CONFIG.H”//****************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************PIN 0低/ /测试“显示”TrISDITS.TrISD1＝0；LabdBist.LaDd1＝1；//-----输入配置------------TrISDITS.TrISD6＝1；//SET引脚6（SW1）作为输入CNPUBITS.CNPUD6＝1；/ /启用内部上拉电阻CNCONDITS.ON＝1；//CNCOND＝32768；/ /允许对所选CN-PI中断。NN CNDNITS.CNIDE6＝1；//启用PIN 6 IFS1BIT.CNDIF＝0的更改通知；/ /清除中断标志IPC8BITS.CNIP＝7；IEC1BIT.CNDY＝1；定义＊＊-------------------------------------DB，DeBung延迟函数。-------------------------------*/ValueDB（int延迟）{int i＝0；对于（i＝0；i & lt；延迟；i++）；}//***************中断例程***************空ixr（αchange change EnguleEx向量，iPL7SRS）.CN中断（空隙）{IFS1BIT.CNDIF＝0；DB（100）；IF（PORTD）位。RD6＝＝0）{LaLDBIT.LATD0＝1；}

    Hello PIC Guru's

I'm trying to get a change notification interrupt to work on the PIC32mx470f512L device, and I'm having a bit of an issue. I don't think the ISR is being called correctly.

The Program function is simple:
                      1) I configure pin 0 and 1 on port D as out put, and turn pin 1 high
                      2) I configure pin 6 on PORT D as an input, and then configure it to receive interrupts.

Step 2, from what I understand requires that I change  a total of 7 registers (TRIS,CNPU,CNCON,CNEN,IFS1,IPC8, and IEC), which I have done. However, I don't think the ISR is actually being called. I made a  debounce function (dB()) for a delay.

Thanks for your time!
