AM263x MCU+ SDK  09.02.00
Release Notes 08.00.02

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.
Unless explicitly noted otherwise, the SW modules would work on any of the R5F's present on the SOC.
