3.3 PAL PTA
The PAL PTA layer provides the support to use the Packet Transmission Arbitration(PTA) feature supported as part IEEE 802.15.4 Standalone PHY Driver.
The implementation design is systematized into two modules
- PTA Interface module
- PTA API module
The PTA Interface module delivers the core system functionality of the PTA feature which is used by IEEE 802.15.4 PHY Driver to deliver the PTA functionality, managing PTA requests and abort scenarios when the feature is activated. Meanwhile, the PTA API module offers the capability to configure the parameters associated with PTA and the debug information of the request, grant and abort count.
