Thermal Sensor Enable (TSE):
This bit enables power to the thermal sensor. Lockable via TCO
bit 7.
0 = Disabled
1 = Enabled
Reserved
Digital Hysteresis Amount (DHA):
This bit determines whether no offset, 1 LSB, 2... 15 is used for
hysteresis for the trip points.
0001 = 1 TR value added to each trip temperature when tripped
0010 = 2 TR values added to each trip temperature when
tripped
...
0110 ~3.0°C (Recommended setting)
...
1110= 14 TR value added to each trip temperature when
tripped
1111 = 15 TR values added to each trip temperature when
tripped
Note: TR = Temperature Read
Reserved
In Use (IU):
Software semaphore bit. After a full MCH RESET, a read to this
bit returns a 0. After the first read, subsequent reads will return
a 1. A write of a 1 to this bit will reset the next read value to 0.
Software can poll this bit until it reads a 0, and will then own the
usage of the thermal sensor.
Writing a 0 to this bit has no effect.
