Memory Map¶
The devices supported by the SimpleLink CC13xx/CC26xx SDK each contains several memory regions including RAM, ROM, and Flash. This section aims to show how these memory regions are utilized by the stack and user application.
The stack library configuration memory map can be seen below. See Stack Library Configuration for more information on the configuration.
