7.7.4 Cyclic and acyclic communication via CTT2
Via CTT2 (Combined Transaction Type 2), both cyclical and acyclical communication is
performed via AS-i. Because only one channel is available (AS-i.DO1 master → slave or AS-i.DI3
slave → master), a concurrent cyclical and acyclical data exchange is not possible.
The communication type (cyclical or acyclical) is always coded in the 󹪝rst byte in accordance
with the following table.
