This bit is used for debug purposes only.
Power-down the thermal temp sensor block.
Set to operate thermal temp sensor with less power.
Add offset to the programmed trip point. 00 adds 5degC, 01 adds 10degC, 10 subtracts 5degC, 11 subtracts
10degC. These are valid only when HW_POWER_THERMAL_OFFSET_ADJ_ENABLE=1
Enable the offset adjustment capability.
This field programs the thermal reset trip point. A value of 000 sets to 115degC and 111 sets to 150degC.
The intermediate values are in steps of 5degC. When TEST=1, all the trip points are set to 65degC less
than their programmed values.
