MCF5206e and timers

Im having some problems getting the timers operational on my 5206e chip.

TCN1 is always 771 [0x0303] so I don’t think my timer is actually counting??

All help and pointers would be greatly appreciated.

      IMR = IMR & ~TIMER1_IMR;      /* remove the interrupt mask for T1 */

      ICR9 = 0x84;                        /* timer 1 = AVEC / IL1 / IP0 [vec25] */

      TRR1 = 0xFFFF;                      /* counter target */

      TCN1 = 0x00;                        /* reset the counter */

      TER1 = 0x03;                        /* clear CAP and REF */

      TMR1 = 0xff3B;                      /* prescaler=FF / NoCap / autoRestart / use MasterSysClk / reset */

      static volatile WORD TCNData;

      while (1)

      {

            TCNData = TCN1;

            asm ("nop");

      }
