Gettemp0() And Gettemp1() Error Codes - Intel BFCBASE - Motherboard - 7300 Datasheet

Prior to a power on RESET# and during RESET# assertion, PECI is not guaranteed 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 damaging states. If the Host controller cannot complete a valid PECI
transactions of GetTemp0() with a given PECI device over 3 consecutive failed
transactions or a one second max specified interval, then it should take appropriate
actions to protect the corresponding device and/or other system components from
overheating. The host controller may also implement an alert to software in the event
of a critical or continuous fault condition.
