LPC2103 timer interrupt

Hi there.

I have a problem with timer interrupt on LPC2103. I want to set timer interrupt on Timer1.

Timer1 and VIC are initialized with this code:

  void TimerInit(void)
      {
          T1PR  = 0x0000000E;
          T1MR0 = 100;
          T1MCR   |=0x00000003;   //Interrupt and Reset on match with MR0
          T1TCR   = 0x00000002;   //Reset counter and prescaler
          T1CTCR  &=0xfffffffc;   //Timer mode
          T1TCR   = 0x00000001;   //Enable timer
      }

   void VICInit(void)
         {
              VICIntEnable = (1 << 5);              // Enables interrupt for TIMER1
              VICIntSelect = 0;                     // All interrupts get classified as IRQ.
              VICDefVectAddr = 0;
              VICVectAddr0 = (unsigned)scheduler;   // Handler for IRQ
              VICVectCntl0 = 0x25;         // Mapping VIC channel
              VICVectAddr = 0;             // Clears the address register
          }

IRQ is set like this:

  B ISR                /* IRQ INTERRUPT */

ISR is defined like that:

 void ISR(void) //to scheduler

{
      //(*((voidfuncptr)VICVectAddr))();

  static int x = 0;
  if (x == 1)
    IOCLR=1<<5;
  else
    IOSET=1<<5;

  x=1-x;
}

It should point to scheduler, but for test, I just wanted to see if ISR occurs.

I think that there is somethink wrong with VICInit. So, why do you thing this code doesn't work?
