This bit toggles at every completed conversion so software can detect a missed or duplicated sample.
Reserved
Set this bit to one to add successive samples to the 18 bit accumulator.
This bit field contains the number of conversion cycles to sum together before reporting operation complete
interrupt status. Set this field to zero for a single conversion per interrupt.
Reserved
This bit field contains the most recent 12-bit conversion value for this channel. If automatic oversampling is
enbled this bit field contains the sum of the most recent N oversampled values, where N is set in the
NUM_SAMPLES field for this channel. When 32 full-scale samples are added together, the 12-bit results
can sum up to 256K. Software is responsible for dividing this value by the number of samples summed
together. Software must clear this register in preparation for a multi-cycle accumulation.
