Power

---

The Power provides functions for getting power wakeup reason.

Required Header

#include <hal-device-power.h>

Overview

The Power provides the way to get power wakeup reason.

The Power functions provide power information including:

• Load/Unload for power hal-backend module
• Getter for power wakeup reason

For more information on the Power features and the macros, see HAL Power programming guides and tutorials.
