Bits 9:0 – AOFF[9:0] Analog Offset
Defines the analog offset to be used for channel CSEL (configured in the AFEC Channel Selection Register). This value is used as an input value for the DAC included in the AFE.
Note:
The field AOFF must be configured to 512 (mid scale of the DAC) when there is no offset error to compensate. To compensate for an offset error of n LSB (positive or negative), the field AOFF must be configured to 512 + n.
