单片机高手请进！！！！！！！
这是编译警告：
*** WARNING L5: CODE SPACE MEMORY OVERLAP
FROM: 0003H
TO: 0005H
以上两个地址冲突了，我定义了2个外部中断函数，应该是interrupt 0这边出了问题。
看keil help文档半天，还是不知道怎么处理这儿问题，请教会的
void Paper_Position_INT0(void) interrupt 0
{
Advance_Plus++;
}
void Seal_Position_INT1(void) interrupt 2
{
Seal_Run_Plus++;
}
网上的处理方法是去掉 Starup.A51。
Source group组下面的Starup.A51已经删掉，以下是部分M51文件:
