C51单片机，定时器1，流水灯！为啥定时器不启动？代码哪里有问题呢？

Question

#include "reg52.h"
#define LED P1 

typedef unsigned int u16;

void Timer1Init(void)
{
    TMOD = 0x10;   
    TH1 = (65536-50000)/256;
    TL1 = (65536-50000)%256;
    ET1 = 1;
    EA = 1;
    TR1 = 1;
}

int main(void)
{
    Timer1Init();
    LED = 0x80;
    while(1);
    return 0;
}

void Timer1(void) interrupt 1
{    
    static u16 count = 0;
    TH1 = (65536-50000)/256;
    TL1 = (65536-50000)%256;
    count++;
    if(count==2)
    {
        LED = LED>>1;
        count = 0;
        if(LED == 0x01);LED = 0x80;
    }
}

Answer 1

35行改成
if(LED == 0x01) LED = 0x80;
中间多了一个；
