6.1
A diagram of the ZL5011x device is given in Figure 15, which shows the major data flows between functional
components.
6.2
There are numerous combinations that can be implemented to pass data through the ZL5011x device depending
on the application requirements. The Task Manager can be considered the central pivot, through which all flows
must operate. The Task Manager acts as a “router” in the centre of the chip, directing packets to the appropriate
blocks for further processing. The task message contains a pointer to the relevant data, instructions as to what to
do with the data, and ancillary information about the packet. Effectively this means the flow of data through the
device can be programmed, by setting the task message contents appropriately.
