ADCO
Continuous Conversion Enable
Enables continuous conversions.
0 One conversion or one set of conversions if the hardware average function is enabled, that is,
AVGE=1, after initiating a conversion.
1 Continuous conversions or sets of conversions if the hardware average function is enabled, that is,
AVGE=1, after initiating a conversion.

AVGE
Hardware Average Enable
Enables the hardware average function of the ADC.
0 Hardware average function disabled.
1 Hardware average function enabled.
AVGS Hardware Average Select
Determines how many ADC conversions will be averaged to create the ADC average result.
00 4 samples averaged.
01 8 samples averaged.
10 16 samples averaged.
11 32 samples averaged.
34.3.8 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 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 Calibration
function section.
