Register 10: ADC Sample Averaging Control (ADCSAC), offset 0x030
This register controls the amount of hardware averaging applied to conversion results. The final
conversion result stored in the FIFO is averaged from 2
specified ADC speed. If AVG is 0, the sample is passed directly through without any averaging. If
AVG is 6, 64 consecutive ADC samples are averaged to generate one result in the sequencer
FIFO. An AVG = 7 provides unpredictable results.

Description
Reserved bits return an indeterminate value, and should
never be changed.
Specifies the amount of hardware averaging that will be
applied to ADC samples. The AVG field can be any value
between 0 and 6. Entering a value of 7 creates unpredictable
results.
