用中断让八位数码管显示04333125

哪位大神帮看下这个代码有什么问题，为什么在protues仿真中显示不了啊
#include<reg51.h>
#define uchar unsigned char   
uchar i=1;
code uchar tableAll[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f};
code uchar tableXH[]={0,4,3,3,3,1,2,5} ;
code uchar table_p2[]={0x7f,0xbf,0xdf,0xef,0xf7,0xfb,0xfd,0xfe}    ;

void display()
{   
    P2=0xff;
    P0=tableAll[tableXH[i++]];
    P2=table_p2[i++];
    if(i==7)
       i=0;
}

void intr() interrupt 3
{
      
      
      
       TH1=(60536)/256;
       TL1=(60536)%256;   
       display();

}  
void main()
{  
   
   TMOD=0x10;
   TH1=(60536)/256;
   TL1=(60536)%256;
   P0=0x3f;
   P2=0x7f;
   EA=1;
   ET1=1;
   TR1=1;
   while(1);

}
