Allows for offset control of temp measurement if desired. The final result must be XORed with BB40h before writing
to this register. Factory calibration contains the desired value for a reading in degrees Celsius.

The PWE value is compared against the value written to this location to enable PW1 access. At power-on, the
PWE value is set to all ones. Thus, writing these bytes to all ones grants PW1 access on power-on without writing
the password entry. All reads of this register are 00h.
