CC2530_How to make 1ms in modulo mode

I want to make 1ms in modulo mode.

My source is working in free-running mode and up-and-down mode. ( I changed only T3CTL to set another mode)

But it doesn't work in modulo mode.

I don't know what problem is.

#include <ioCC2530.h>
#define LED0 P1_0 
#define LED1 P1_1 
#define LED4 P1_4 

  
volatile int count;

void ledinit()
{
        P1DIR |= ((1<<0)|(1<<1)|(1<<4));  
        LED0 = 0;      
        LED1 = 0;              
        LED4 = 0;             
}

void timer3_init()
{    
T3CTL = 0XFE;           // prescaler 128, start timer, interrupt enable, modulo mode
T3CC0=125;              // modulo mode (0X00~T3CCO)

}

void interrupt_int()
{
      IRCON |= 0x40;  
  
      IEN0 |= 0X80;     
                      
      T3IE=1;         
      T3CCTL0 |=0X40;  
//      T3CCTL1 |=0X40;  

}

#pragma vector = T3_VECTOR

 __interrupt void T3_ISR(void)
 {
  
count++;
        if(count>500)               
        {         
         count = 0;                   
         LED0=~LED0;
         LED1=~LED1;
         LED4=~LED4;
        }
  
  
       
 }

int main()
{ 
      ledinit();  
      timer3_init();
      interrupt_int();
      while(1);
     
}
