• Ping(), GetDIB(), GetTemp() and MbxGet() have no impact on processor power
under C-states. All other commands (MbxSend(), PCIConfigRd() and
PCIConfigWr()) result in the same behavior, as follows:
• MbxSend(), PCIConfigRd() and PCIConfigWr() usage under package C-states may
result in increased power consumption because the processor must temporarily
return to a C0 state in order to execute the request. The exact power impact of a
pop-up to C0 varies by product SKU, the C-state from which the pop-up is initiated,
and the negotiated T
BIT
.
7.3.7.5 S-States
The PECI client is always guaranteed to be operational under S0 and S1 sleep states.
Under S3 and deeper sleep states, the PECI client response is undefined and therefore
unreliable.
7.3.7.6 Processor Reset
Intel Xeon processor 5600 series acting as PECI clients are fully reset on all RESET#
assertions. Upon deassertion of RESET#, where power is maintained to the processor
(otherwise known as a ‘warm reset’), the following are true:
• The PECI client assumes a bus Idle state.
• The Thermal Filtering Constant is retained.
• PECI Node ID is retained.
• GetTemp() reading resets to 0x0000.
• Any transaction in progress is aborted by the client (as measured by the client no
longer participating in the response).
• The processor client is otherwise reset to a default configuration.
7.4 Storage Conditions Specifications
Environmental storage condition limits define the temperature and relative humidity
limits to which the device is exposed to while being stored. The specified storage
conditions are for component level prior to board attached (see following notes on post
board attach limits).
Table 7-38 specifies absolute maximum and minimum storage temperature limits which
represent the maximum and minimum device condition beyond which damage, latent
or otherwise, may occur. The table also specifies sustained storage temperature,
relative humidity, and time-duration limits. At conditions outside sustained limits, but
within absolution maximum and minimum ratings, quality & reliability may be affected.
