Interval Update Rules
More than one threshold control can be set to modify the same timer. In
this case, the following update rules for setting a new interval are
applied:
- New interval is shorter than the currently effective one.
- Setting a threshold control has a higher priority than the currently
effective one.
- New interval is set by the same threshold control than the currently
effective one.
- This is the first update.
NOTE High-priority threshold control can release the timer for others to
update by setting the value -1 to the interval.
