data (with the exception of error codes) and the relative
temperatures are listed for reference only. Table 12
shows the values with 16-bit and alternate word format.
The read maximum temperature command from Table 11
returns the highest temperature that is not an error
code from the enabled PECI sockets and domains. This
operation works on signed numbers only and does not
give information as to what socket the temperature
result comes from. To find the socket and domain, use
the read maximum temperature address command as
shown in Table 13.
Table 13. Read Maximum Temperature
Address
The read maximum temperature address command
returns the register that had the highest temperature
when read maximum temperature was last called. An
error is returned if the read maximum temperature has
not been called or when the read maximum tempera-
ture itself returns an error.
Figure 4 shows the operations performed on tempera-
ture data read through PECI.
