5.6 AMD TSI and Intel PECI 3.0 Functions  
The F71869A provides Intel PECI/AMD TSI 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.

Figure 18 AMD TSI typical application  
In Intel PECI interface, the F71869A can connect to CPU directly. The F71869A can read the  
temperature data from CPU, than the fan control machine of F71869A can implement the Fan to  
cool down CPU temperature. The application circuit is as below.
