* MSP432 CODE EXAMPLE DISCLAIMER
*
* MSP432 code examples are self-contained low-level programs that typically
* demonstrate a single peripheral function or device feature in a highly
* concise manner. For this the code may rely on the device's power-on default
* register values and settings such as the clock configuration and care must
* be taken when combining code from several examples to avoid potential side
* effects. Also see http://www.ti.com/tool/mspdriverlib for an API functional
* library & https://dev.ti.com/pinmux/ for a GUI approach to peripheral configuration.
