23.4.8 ADC Offset Correction Register (ADCx_OFS)
The ADC Offset Correction Register (OFS) contains the user-selected or calibration-
generated offset error correction value. This register is a 2's complement, left-justified,
16-bit value . The value in OFS is subtracted from the conversion and the result is
transferred into the result registers, Rn. If the result is greater than the maximum or less
than the minimum result value, it is forced to the appropriate limit for the current mode of
operation.
For more information regarding the calibration procedure, please refer to the
function
section.
Address: 4003_B000h base + 28h offset = 4003_B028h
