加了定时器初始化 端口赋值就不变了或者跟赋值的数不同是为什么？

[forget345]

定时器终端服务程序看看

[FBIIIC]

只写了初始化，发现端口不会变化

[zgl7903]

C8051F 系列单片机的 P4，P5，P6，P7 要先 SFRPAGE = 0x0F， 再访问

[FBIIIC]

不行啊，SFRPAGE = 0x0F加在while里会报错，加在while前也会报错

[FBIIIC]

不好意思，是我忘记加分号了，可以了，感谢感谢

[FBIIIC]

void Timer1() interrupt 3
{
TH1=0x4d;
TL1=0x6e;
led1=1;
P5=0x00;
}

我现在用定时器1进中断点亮 但是没有反应，这是哪里的问题？
