标题: xs128中断程序
本人菜鸟一枚
有哪位大神  给说说 xs128的中断程序该怎么写啊  查了许多资料  说的也不清楚还不一样
#pragma CODE_SEG NON_BANKED
void  interrupt 20 SCI0_re(void)
{
unsigned char ch;
ch=SciRead();
SciWritestring(&ch);
}
  比如说这样写可以不？？？
还有我一直有个疑问：中断程序写的格式是不是只取决于cw的版本啊？？？

#pragma CODE_SEG __NEAR_SEG NON_BANKED 中断程序要放在非分页区
                                             这句话意思是后面的程序放在非分页区
void interrupt 16 INT_Timer0(void)                            中断格式对应中断号16

{
PORTB++;                                                          自己的代码

TFLG2_TOF=1;                                                    //清中断标志位
}
#pragma CODE_SEG DEFAULT                         这句话意思是后面的程序放在正常存放区

中断定义在MC9S12XS128.h里找（见下）
