Platform Environment Control Interface (PECI)
The PECI is a one-wire interface that provides a communication channel between
processor and a PECI master, usually the PCH. The processor implements a PECI
interface to:
processor and a PECI master, usually the PCH. The processor implements a PECI
interface to:
• Allow communication of processor thermal and other information to the PECI
master.
• Read averaged Digital Thermal Sensor (DTS) values for fan speed control.
