NPI Peripheral Sub System

The Wireless Network Processors can be used for much more than a radio network processor. There are usually several peripherals available on-chip. To allow host easy access to control these peripherals we have a separate Sub-System for Peripherals. We use the Command ID field to differentiate between different Sub-Sub-Systems within the Peripheral Sub-System.

There are two different ways the Command ID field is used.

1. The 5 LSBs identify the Sub-Sub-System
   1. The 3 MSBs are set to 000
   2. APIs are identified inside the payload of the General NPI Frame Format
2. The 3 MSBs identify the Sub-Sub-System
   1. The 3 MSBs cannot be 000
   2. APIs are identified by the 5 LSBs of the Command ID

Click on the Sub-Sub-System to get a list of the supported APIs.
