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 to. The
Load register should not be written to after the Timer is enabled as this causes
the Timer Value register to be updated with an undetermined value.
Load:
Timer1 - 0x8081_0004 - Read Only
Timer2 - 0x8081_0024 - Read Only
0x0000_0000
The Value location gives the current value of the timer. When the Timer Load
register is written to, the Value register is also updated with this Load value.
