F71862
and timing sequence of each signal is as below:
7.9 AMDSI and Intel PECI Function
The F71862 provides Intel PECI/AMDSI interfaces for new generational CPU temperature
sensing. In AMDSI interface, there are SIC and SID signals for temperature information reading
from AMD CPU. The SIC signal is for clocking use, the other is for data transferring. More detail
please refer register description.
