31.3.8 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 the offset correction registers (OFS) is subtracted from the
conversion and the result is transferred into the result registers (Rn). If the result is above
the maximum or below the minimum result value, it is forced to the appropriate limit for
the current mode of operation.
Addresses: ADC0_OFS is 4003_B000h base + 28h offset = 4003_B028h
