中断入口是什么意思哦？

中断到底是啥啊

用过用interrupt n写的话，不用在prm程序里加中断向量，如果只有interrupt则需要在prm文件中把函数名加在里面。

<>老大！不知道怎么用这个来用C语言编程啊！</P><P>比如要编一个IOC0的中断程序；它的地址是0x0000FFEE；</P><P>是不是这样定义哦？</P><P>void interrupt&nbsp; &nbsp;Vtimch0(void)&nbsp;&nbsp;<BR></P>

<>不是，中断号就是改中断向量相对于复位中断向量的偏移量。</P><P>比如复位向量是$FFFE,ATD0是是$FFD2，偏移量是22，所以ATD0的中断号是22。就这样定义中断函数就可以了。</P>
