1、背景介绍
目前采用国产ZYNQ替代进口xilinx ZYNQ，在调试PL-PS的中断时，和进口Xilinx ZYNQ有区别，记录如下。
2、vivado工程
直接引入一个GPIO输入ZYNQ PL-PS
ZYNQ中配置PL-PS中断
此时vivado工程配置完毕
3、procise工程
由于国产ZYNQ与进口ZYNQ还是存在区别，PL-PS的中断号和进口的不一样，需要在procise中查看实际的中断号。
Procise从vivado中导入文件，产生国产ZYNQ的硬件连接关系，导入后点击ZYNQ能看到PL-PS的中断序号已经改变了
国产的前8个中断号是从57-64，而进口的是从61-68.
4、SDK代码
从procise中导出工程到IAR中，代码如下，中断方式为上升沿触发。

注意中断号从57开始
