MEC1501 RTOS timer internal counter is on the 32KHz clock domain.
The register interface is on the AHB clock. When the timer is started
hardware synchronizes to the next 32KHz clock edge resulting is a
variable delay moving the value in the preload register into the
count register. The maximum delay is one 32KHz clock period (30.5 us).
We work-around this delay by checking if the timer has been started
and not using the count value which is still 0. Instead we state zero
counts have elapsed.
