§Hardware and Software Reset

§Overview

Espressif chips provide four types of reset that occur at different levels, namely CPU Reset, Core Reset, System Reset, and Chip Reset. All reset types mentioned above (except Chip Reset) preserve the data stored in internal memory.

The Hardware and Software Reset module provides functions for performing hardware and software resets and includes functions for retrieving the reset reason and the wakeup cause after a reset.

The module defines a set of sleep sources (SleepSource) that indicate the source of the wakeup event. It also includes a set of flags (WakeupReason) that represent different wakeup sources and enable/disable wakeup triggers for specific events.
