#include "reg52.h"

sbit led1 = P2^0;

unsigned int cnt = 0;

void Timer0Init();

void main()
{
Timer0Init();
while(1)
{

}
}

void Timer0Init() //定时1ms，11.0592M
{
TMOD = 0X01;
TL0 = 0XCD;
TH0 = 0XD4;
TR0 = 1;
TF0 = 0;
ET0 = 1;
EA = 1;
}

void Timer0() interrupt 1
{
TL0 = 0XCD;
TH0 = 0XD4;

cnt++;
if(cnt>=100)
{
cnt = 0;
led1 = ~led1;
}

}
