Temperature Commands
Table 11 shows the different commands for selecting
one of the PECI hosts or getting the maximum tempera-
ture. Read commands are initiated by the MAX6618,
and the result returned is a 16-bit word with the least
significant bit (LSB) clocked in first for the selected
PECI host.
The result consists of RESLO for the 8 LSBs and RESHI
for the 8 MSBs, resulting in a 16-bit word. The 16-bit
words are temperature values read from the PECI
interface. PECI-enabled Intel microprocessors return
temperature data in fractions of 1°C below the thermal-
control-circuit activation point, resulting in negative
return values that do not represent absolute tempera-
tures. Absolute temperatures can be achieved by set-
ting the temperature offset in CONFIG2.
Table 12 shows example return values for an Intel CPU.
Note that the MAX6618 does not interpret the return
