OFS Offset Error Correction Value
34.3.9 ADC Plus-Side Gain Register (ADCx_PG)
The Plus-Side Gain Register (PG) contains the gain error correction for the plus-side
input in differential mode or the overall conversion in single-ended mode. PG, a 16-bit
real number in binary format, is the gain adjustment factor, with the radix point fixed
between PG[15] and PG[14]. This register must be written by the user with the value
described in the calibration procedure. Otherwise, the gain error specifications may not
be met.
For more information regarding the calibration procedure, please refer to the Calibration
function section.

34.3.10 ADC Minus-Side Gain Register (ADCx_MG)
The Minus-Side Gain Register (MG) contains the gain error correction for the minus-side
input in differential mode. This register is ignored in single-ended mode. MG, a 16-bit
real number in binary format, is the gain adjustment factor, with the radix point fixed
between MG[15] and MG[14]. This register must be written by the user with the value
described in the calibration procedure. Otherwise, the gain error specifications may not
be met.
For more information regarding the calibration procedure, please refer to the Calibration
function section.
