<p>The MCUXpresso SDK provides a peripheral driver for the Secure Non-Volatile Storage Low-Power (SNVS-LP) module.<br/>
<br/>
The SNVS_LP is a data storage subsystem. Its purpose is to store and protect system data, regardless of the main system power state. The SNVS _LP is in the always-powered-up domain, which is a separate power domain with its own power supply. <br/>
