for(;;) {

} /* wait forever */
/* please make sure that you never leave this function */
}

void interrupt 8 ECT_IC0(void)

{
PORTB=0x0f;
TFLG2_TOF= 1;
for(;;){

PORTB=0xf0;
}
// TFLG2_TOF = 1; //clear timer overflow flag
//用户自己的代码
}
程序功能:
想要程序计数定时进入中断程序执行~
谢谢斑竹!!

你要的应该是定时器溢出中断而不是IC0中断。溢出中断TOF的中断号为16。
