How can I enable the compound clocking in the TLA application software v5.6?

The compound clocking is not implemented in the v5.6 software yet.  If you need compound clocking, you will need to use the v5.1 SP1 software.  However, if you have a saved setup file created in v5.1 SP1 software, you will still be able to use the compound clocking.  However, you will not be able to modify it.
