The Backlight API allows developers to control the backlight
(screen) in embedded devices.
A watchdog timer is a device that performs a specific opera-
tion after a specified period of time when a malfunction
occurs and the system cannot recover on its own. A watch-
dog timer can be programmed to perform a warm booting
(system restart) after a certain number of seconds.
The Hardware Monitor API is a system health supervision
API that inspects certain condition indices, such as fan
speed, temperature, and voltage.
This feature uses Intel SpeedStep® Technology to reduce
the system power consumption. The system automatically
adjusts the CPU speed according to the system load.
This refers to a series of methods for reducing system power
consumption by lowering the clock frequency. This API
allows users to adjust the clock frequency from 87.5% to
12.5%.
