单片机定时器, TI, TE, ov, unsigned

各位大哥帮我看下，义隆153单片机，定时器计数溢出无法进入中断，哪里配置不对呢？
#include "interrupt_vector.h"
#include "EM78P153A.h"
#define LED PORT6

void delay(unsigned short);
void main(void)
{
      unsigned int i;
      WDTCR=0;
      TCC = 0;
      P6CR = 0Xf0;
//       IMR = 0x01;
      _asm{
            MOV    A, @0x01          ; 允许计数器中断
      IOW    0xf
      ENI                   ; 开中断
      }
      ISR = 0;
      _asm
            {
                     mov a,@0x04
                     contw
            }
      while(1)
      {
            for(i=7;i>0;i--)
            {
                     LED = i;
                     delay(60000);
            }
      }

}
void delay(unsigned short i)
{
      unsigned short j;
      for(j=0;j<60000;j++)
      {
            for(;i>0;i--)
            {
                     ;
            }
      }
}
void _intcall interrupt(void) @ int
{
      ISR = 0;
      _asm
         {
                  reti          //Tell Compiler to recover common registers here.
                                                                           //Don't remove or duplicate this instruction in this function
         }
}
