The Load register contains the initial value of the timer and is also used as the
reload value in periodic timer mode. The timer is loaded by writing to the Load
register when the timer is disabled. The Timer Value register is updated with
the Timer Load value as soon as the Timer Load register is written. The Load
register should not be written after the Timer is enabled because this causes
the Timer Value register to be updated with an undetermined value.
