The digital value used for the HBIAS1 reference and recalled from Table 06h (Registers E0h–E7h) (transmitter 1) at
the adjusted memory address found in TINDEX. This register is updated at the end of the temperature conversion.
Comparisons greater than VHBIAS1 compared against VBMON1 create an HBAL alarm.
