The host system, typically containing an application microprocessor, can control the
operation of the AT90RF135602 by interfacing commands and application data over a
bi-directional Serial Peripheral Interconnect (SPI) interface.
The partitioning of the system into its typical protocol layers is shown in Figure 2.
The exact boundary of each layer of the protocol stack is dependent on the specific
application and, therefore, the optimal architectural split of the protocol layers.
Software implementation of the protocol stack allows for operation with multiple parallel
stacks as well as greater flexibility for customisation and future updates.
