======== ccfg.c ========
* Customer Configuration for CC26xx and CC13xx devices. This file is used to
* configure Boot ROM, start-up code, and SW radio behaviour.
*
* By default, driverlib startup_files/ccfg.c settings are used. However, if
* changes are required there are two means to do so:
*
* 1. Remove this file and copy driverlib's startup_files/ccfg.c file in
* its place. Make all changes to the file. Changes made are local to
* the project and will not affect other projects.
*
* 2. Perform changes to driverlib startup_files/ccfg.c file. Changes
* made to this file will be applied to all projects. This file must
* remain unmodified.
