Change the gain value for input amplifier
(called PGA) of the converter. The value of
this register is significant only for the analog
inputs configured as countings (SM123..126
= 19). This register is managed by bit, but
not all bit can be modified:

OFFSET register for A/D converter
(default 0)
Enter an offset value for the input of internal
A/D converter. The value of this register is
significant only for the analog inputs
configured as countings (SM40..43 = 19).
This register is managed by bit, but not all bit
can be modified:
R/W
Sign of offset value:
0
Positive Offset
1
Negative Offset
Input offset value:
Offset (Volt) = (VREF * Offset value) /
(254 * PGA)
