Synthetic Timer Count Register

The following tables show how the synthetic timer count registers are encoded.

The value programmed into the count register is a time value measured in 100 nanosecond units. Writing the value zero to the count register will stop the counter, thereby disabling the timer, independent of the setting of the AutoEnable bit in the configuration register. For more information about this bit, see Synthetic Timer Configuration Register.

Note that the count register is permitted to wrap. Wrapping will have no effect on the behavior of the timer, regardless of any timer property.

For one-shot timers, the count value represents the absolute timer expiration time. The timer expires when the reference counter for the partition is equal to or greater than the specified count value.

For periodic timers, the count value represents the period of the timer. The first period begins when the synthetic timer is enabled.
