PECI Interface
88 Thermal/Mechanical Specifications and Design Guide
7.1.4.12.3 WrPCIConfigLocal() Capabilities
On the processor PECI clients, the PECI WrPCIConfigLocal() command provides a
method for programming certain memory controller functions as described in
Tab l e 7 -1 6 . Refer to the Intel
®
Core™ i7 Processor Family for the LGA-2011 Socket
Datasheet, Volume 2 for more details on specific register definitions. It also enables
writing to processor REUT (Robust Electrical Unified Test) registers associated with the
Intel® QPI, PCIe* and DDR3 functions.
7.1.5 Client Management
7.1.5.1 Power-up Sequencing
The PECI client will not be available when the PWRGOOD signal is de-asserted. Any
transactions on the bus during this time will be completely ignored, and the host will
read the response from the client as all zeroes. PECI client initialization is completed
approximately 100µS after the PWRGOOD assertion. This is represented by the start of
the PECI Client “Data Not Ready” (DNR) phase in Figure 7-44. While in this phase, the
PECI client will respond normally to the Ping() and GetDIB() commands and return the
highest processor die temperature of 0x0000 to the GetTemp() command. All other
commands will get a ‘Response Timeout’ completion in the DNR phase as shown in
Tab l e 7 -1 7 . All PECI services with the exception of core MSR space accesses become
available ~500 uS after RESET_N de-assertion as shown in Figure 7-44. PECI will be
fully functional with all services including core accesses being available when the core
comes out of reset upon completion of the RESET ucode execution.
