Controls the scaling or gain of the full-scale voltage measurements. The factory-calibrated value produces an
FS voltage of 6.5536V for VCC, 2.5V for RSSI2 COARSE and RSSI1 COARSE, and 0.3125V for RSSI2 FINE and
RSSI1 FINE.

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.
