3. R4 SCbus Routing API for DM3

NOTE:

When this document refers to the SCbus, SCbus resource or SCbus routing, the information also applies to the CT Bus on DM3 products. That is, the physical interboard connection can be either SCbus or CT Bus. The SCbus protocol is used and the SCbus routing API applies to all the boards regardless of whether they use an SCbus or CT Bus physical interboard connection.
