notes: |
If the period name is not unique, then the period identifier will match the
first period with that name in the search order. However, this period
identifier is not guaranteed to correspond to the desired period.
The objects are searched from lowest to the highest index. Only the local
node is searched.
The period identifier is used with other rate monotonic related directives to
access the period.
