Detailed Description

Energy Modes management driver.

Version

5.1.2

This is a energy modes management module consisting of sleep.c and sleep.h source files. The main purpose of the module is to ease energy optimization with a simple API. The module allows the system to always sleep in the lowest possible energy mode. Users could set up callbacks that are being called before and after each and every sleep. A counting semaphore is available for each low energy mode (EM1/EM2/EM3) to protect certain system states from being corrupted. This semaphore has limit set to maximum 255 locks.

The module provides the following public API to the users: SLEEP_Init() SLEEP_Sleep() SLEEP_SleepBlockBegin() SLEEP_SleepBlockEnd() SLEEP_ForceSleepInEM4()
