function and codes.

5.3.2.3

PECI Fault Handling Requirements

PECI is largely a fault tolerant interface, including noise immunity and error checking

improvements over other comparable industry standard interfaces. The PECI client is

as reliable as the device that it is embedded in, and thus given operating conditions

that fall under the specification, the PECI will always respond to requests and the

protocol itself can be relied upon to detect any transmission failures. There are,

however, certain scenarios where the PECI is know to be unresponsive.

Prior to a power on RESET# and during RESET# assertion, PECI is not assured to

provide reliable thermal data. System designs should implement a default power-on

condition that ensures proper processor operation during the time frame when reliable

data is not available via PECI.

To protect platforms from potential operational or safety issues due to an abnormal

condition on PECI, the Host controller should take action to protect the system from

possible damage. It is recommended that the PECI host controller take appropriate

action to protect the client processor device if valid temperature readings have not

been obtained in response to three consecutive GetTemp()s or for a one second time

interval. The host controller may also implement an alert to software in the event of a

critical or continuous fault condition.

5.3.2.4

PECI GetTemp0() Error Code Support
