The BIAS LUT is a set of registers assigned to hold the temperature profile for the BIAS reference DAC. The
temperature measurement is used to index the LUT (TINDEX, A2h Table 02h, Register 81h) in 2NC increments.
Values recalled from this EEPROM memory table are written into the BIAS or SET_IBIAS location, which holds the
value until the next temperature conversion. The part can be placed into a manual mode, where BIAS or SET_IBIAS
can be directly controlled for calibration. If TE temperature compensation is not required by the application,
program the entire LUT to the desired BIAS value.
