SB Temperature Sensor Interface (SB-TSI) is an SMBus compatible
|
|
interface that reports AMD SoC's Ttcl (normalized temperature),
|
|
and resembles a typical 8-pin remote temperature sensor's I2C interface
|
|
to BMC. The emulated thermal sensor can report temperatures in increments
|
|
of 0.125 degrees, ranging from 0 to 255.875.

I2C bus address of the device as specified in Section 6.3.1 of the
|
|
SoC register reference. The SB-TSI address is normally 98h for socket
|
|
0 and 90h for socket 1, but it could vary based on hardware address
|
|
select pins.
