Register 12: 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
AVG
consecutive ADC samples at the specified
ADC speed. If AVG is 0, the sample is passed directly through without any averaging. If AVG=6,
then 64 consecutive ADC samples are averaged to generate one result in the sequencer FIFO. An
AVG=7 provides unpredictable results.

DescriptionResetTypeNameBit/Field
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

Hardware Averaging Control
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.
