The digital value used for the HTXP2 reference and recalled from Table 06h (Registers E8h–EFh) (transmitter 2) at
the adjusted memory address found in TINDEX. This register is updated at the end of the temperature conversion.
Comparisons greater than VHTXP2 compared against VPMON2 create a TXP HI alarm.
