Help on Timer0 interrupt in 2214

I have a problem in firing the inteerupt in ISR.I have posted my source code here for your ref.Iam checking for a flag, in main()- while()loop, which is never enabled in TIMER0 ISR.But when i used polling mode its working fine. So I think I definately missing some things some where. I have used this timer ISR to trigger for every 10seconds.

Environment: Eclipse/GNUARM/LPC2214…

I didnt do any thing related to this ISR in any of the startup file and linker script…Please help me on this.

{

T0PC = 0; // Prescaler is set to no division.

T0MR0 = 0xE666; //PCLKFREQ/1000; // Count up to this value. Generate 1000 Hz interrupt.

T0MCR = 3; // Reset and interrupt on MR0 (match register 0).

T0CCR = 0; // Capture is disabled.

T0EMR = 0; // No external match output.

T0TCR = 1; // Enable timer 0.

VICIntSelect &= ~(0x10); // IRQ on timer 0 line.

VICVectAddr1 = (unsigned int)TimerInterrupt;

VICVectCntl1 = 0x20 | 0x04; // Enable vector interrupt for timer 0.

VICIntEnable = 0x10; // Enable timer 0 interrupt.

}

// Timer interrupt handler

T0IR = 0xff; // Clear timer 0 interrupt line.

}

//Dummy interrupt handler, called as default in irqHandler() if no other vectored interrupt is called.
