關于51單片機T2中斷的問題

請問為什么我的程序不能實現T2定時閃爍功能，如果我加上T2MOD=0的話會報錯；求大佬指點
#include<reg52.h>
#define led P2
typedef unsigned char uchar;
typedef unsigned int uint;

uint count;

void Timer2Init(void) //50??@12.000MHz
{
   //T2MOD = 0; //????????
T2CON = 0; //????????
TL2 = 0xB0; //??????
TH2 = 0x3C; //??????
RCAP2L = 0xB0; //???????
RCAP2H = 0x3C; //???????
EA=1;
ET2=1;
TR2 = 1; //???2????
}

void init() interrupt 5
{
count++;
if(count==20)
{
count=0;
led=~led;
}
}

void main()
{
   Timer2Init();
   while(1);
}
