LPC17xx Interrupt

Hi everyone

I wrote a simple program for timer0 of lpc1768 it works but I do not know after the interrupt what to do and how can I jump to vector address of timer0 , the interrupt state is pending
how can I change it to active

Another question
Is it necessary to move vector table

Here is my code

     #include "lpc17xx.h"

int main (void) {




  LPC_TIM0->CTCR = 0x00;             /*timer0 in timer mode*/

  LPC_TIM0->PR = 2;

  LPC_TIM0->TC=0x0;

  LPC_TIM0->TCR= 0x00000001;

   LPC_TIM0->MR0=6;

   LPC_TIM0->MCR=5;
}
