6410的外部中断为EXINT0~27（GROUP0）,Ext.InterruptGroup1~Ext.InterruptGroup9,从Ext.InterruptGroup1到Ext.InterruptGroup9每一组都有若干个中断。除了EXINT0~27每一个中断都有一个中断号对应一个中断，外部中断组EXINTGROUP[1]~EXINTGROUP[9]都使用同一个中断号#defineIRQ_RESERVED91//53。
如果我使用GPO6（Ext.InterruptGroup7[6]）和GPP8（Ext.InterruptGroup8[8]）我的中断线程初始化应该怎么设置呢？请各位大师指点啊！！！！
下面是GPO6的中断设置
