controller has Low and High temperature offsets available for calibration of the internal

registers for A.L.P, the low temperature calibration point, A.L.o, the low temperature point offset
(or correction); A.H.P, the high temperature calibration point and A.H.o, the high temperature
point offset (or correction).
