Data and Control Flows
There are numerous combinations that can be implemented to pass data through the ZL50110/11/12/14 device
depending on the application requirements. The Task Manager can be considered the central pivot, through which
all flows must operate.
The flow is determined by the Type field in the Task Message (see ZL50110/11/12/14 Programmers Model).
Each of the 11 data flows uses the Task Manager to route packet information to the next block or interface for
onward transmission. This section describes the flows between the TDM interface, the packet interface and the
Task Manager which are the main flow routes used in the ZL50110/11/12/14 family. For example, the TDM->TM
flow is used in flow types 1, 3, 5, and 6, and the TM->PKT flow is used in flow types 1, 3, and 9.
