3.4 PAL PTA Configuration

This setion provides the MCC design details to configure and support the PTA feature into the project.

The Configuration to enable PTA configuration is provided in the Device Support Library Component as shown below.

The IEEE 802.15.4 PTA supports two interface modes

  1. 3-Wire PTA
  2. 2-Wire PTA

As the names suggest, the 3-Wire PTA necessitates three pins to activate the PTA feature, while the 2-Wire PTA requires only two pins to accomplish the same functionality. The PTA pin configurations are initially mapped to certain pins by default, but they can be customized to meet user needs.

The PTA parameter configuration can be found under IEEE 802.15.4 Standalone PHY → Configuration Options. The images below illustrate these configurations.

Figure 3-2. 3-Wire PTA Config
Figure 3-3. 2-Wire PTA config

The configuration parameters shown in the image above are detailed in the table below.
