Attention

Also refer to individual module pages for more details on each feature, unsupported features, important usage guidelines.

Note

The examples will show usage of SW modules and APIs on a specific CPU instance and OS combination.
Unless explicitly noted otherwise, the SW modules would work in both FreeRTOS and no-RTOS environment.
