Controls the scaling or gain of the full-scale voltage measurements. The factory-calibrated value produces an FS
voltage of 6.5536V for V
CC
and 2.5V for BMON2, PMON2, BMON1, and PMON1.

Allows for offset control of temperature 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.
