The high bias alarm threshold (HBATH) LUT is used to temperature compensate the bias QT threshold (HBIAS).
The table below shows the range of temperature for each byte’s location. The table shows a rising temperature;
for a falling temperature there is 1NC of hysteresis.
These registers do not exist.
