Agent to report whether the W83627UHG (PECI host) detects the PECI client or not and whether the
PECI client returns invalid FCS values from the polling for three successive times.
the Bank 1 Index 50h & 51h or Bank 2 Index 50h & 51h reading does not reflect the actual
temperature of the processor.
8. In addition, each PECI Agent relative temperature can be read in Logical Device C, CR[E0h] ~
CR[E7h], as long as Logical Device C, CR[E8h] bit 3 is set to “1”. When this bit is “1”, Logical Device
C, CR[E0h] ~ CR[E7h] become “Read Only” registers.
Please be noted that when the temperature source is selected as PECI temperature source,
9. A warning flag register at Logical Device C, CR[E8h] bit (7..4) is designed for each PECI
