This object indicates the manual switching flag. The 'true' value indicates the currently selected clock source is a result of the manual switch command. The command allows a user to select a synchronization source assuming it is enabled, not locked out, not in signal fail condition, and has a QL better than DNU in QL-enabled mode. Furthermore, in QL-enabled mode, a manual switch can be performed only to a source which has the highest available QL.
