void Timer0Handler (void) __irq
{
  timer_counter++;

  if ( timer_KEYpress != 0 )
    timer_KEYpress--;
  else
    KEYS_check();

  if ( timer_GPIO8LED != 0 )
    timer_GPIO8LED--;

  if ( timer_MSPI7LED != 0 )
    timer_MSPI7LED--;

  T0IR = 1;                     /* clear interrupt flag */
  VICVectAddr = 0;              /* Acknowledge Interrupt */
}
