5.2.2 Series Accumulation with Scaling

Like in the Series Accumulation mode, a SAMPNUM number of samples are in this mode automatically accumulated into a single result. The difference is that in Series Accumulation with Scaling, the result is automatically scaled to a 16-bit value. Scaling is always applied after accumulating the last sample and is carried out by right shifting the accumulated result by SAMPNUM-4 bits.

This mode can simply be used to accumulate and automatically get an averaged result, or it may be used in combination with the oversampling technique as described in Section Oversampling to achieve a 16-bit resolution by accumulating at least 4⁴ = 256 samples and automatically scaling down to 16 bits.
