Platform Environment Control Interface (PECI)

The PECI is a one-wire interface that provides a communication channel between a
PECI client (processor) and a PECI master. 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.
