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 MAX6621,
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 inter-
face. PECI-enabled Intel microprocessors return tem-
perature data in fractions of 1°C below the
thermal-control-circuit activation point, resulting in neg-
ative return values that do not represent absolute tem-
peratures. Absolute temperatures can be achieved by
setting the temperature offset in CONFIG2.
Table 12 shows example return values for an Intel CPU.
Note that the MAX6621 does not interpret the return
