Thermometer Mode Enable and Rate (TE)
If analog thermal sensor mode is not enabled by setting these bits to 0000b,
these bits enable the thermometer mode functions and set the Thermometer
controller rate. When the Thermometer mode is disabled and TSC1[TSC]
=enabled, the analog sensor mode should be fully functional.
In the analog sensor mode, the Catastrophic trip is functional. The other trip
points are not functional in this mode.
When Thermometer mode is enabled, all the trip points (Catastrophic, Hot,
Aux 0, Aux 1, Aux 2 will all operate using the programmed trip points and
Thermometer mode rate.
Note: When disabling the Thermometer mode while the thermometer is
running, the Thermometer mode controller will finish the current cycle.
Note: During boot, all other thermometer mode registers (except lock bits)
should be programmed appropriately before enabling the Thermometer
Mode.
