Note:
The 3-byte PCI configuration address and write data field defined in
are sent in standard PECI ordering with
LSB first and MSB last.

Supported Responses
The typical client response is a passing FCS, a passing Completion Code and valid data.
Under some conditions, the client’s response will indicate a failure.
Under some conditions, the client’s response will indicate a failure.
The PECI client response can also vary depending on the address and data. It will
respond with a passing completion code if it successfully submits the request to the
appropriate location and gets a response.

Response
Meaning
Bad FCS
Electrical error or AW FCS failure
Abort FCS
Illegal command formatting (mismatched RL/WL/Command Code)
CC: 0x40
Command passed, data is valid.
CC: 0x80
Response timeout. The processor was not able to generate the required response in a timely
fashion. Retry is appropriate.
CC: 0x81
Response timeout. The processor is not able to allocate resources for servicing this command
at this time. Retry is appropriate.
CC: 0x82
The processor hardware resources required to service this command are in a low power
state. Retry may be appropriate after modification of PECI wake mode behavior if
appropriate.
CC: 0x90
Unknown/Invalid/Illegal Request
CC: 0x91
PECI control hardware, firmware or associated logic error. The processor is unable to process
the request.
