A2h AND B2h MEMORY
MEMORY TYPE
Controls the scaling or gain of the full-scale voltage measurements. The factory-calibrated value produces an
FS voltage of 6.5536V for V
RSSI1 FINE.

WRITE ACCESS
A2h AND B2h MEMORY
MEMORY TYPE
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.
