初学者51单片机定时疑问

#include<reg52.h>

unsigned int code LedChar[]={
0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,
0x80,0x90,0x88,0x83,0xc6,0xa1,0x86,0x8e
};

void main()
{
unsigned int sec = 0;
while(1)
{
      if(sec<=16)
      {
      P0=LedChar[sec];
InitTimer0();
      sec++;
      }
      sec=0;
}
}

void InitTimer0(void)
{
TMOD = 0x01;
TH0 = 0x0EE;
TL0 = 0x00;
TR0 = 1;
}

错误提示：

我这个InitTimer0函数是用单片机小精灵算出来的，难道还有错不成？
