15.6. CS0 Conversion Accumulator
CS0 can be configured to accumulate multiple conversions on an input channel. The number of samples to
be accumulated is configured using the CS0ACU2:0 bits (CS0CF2:0). The accumulator can accumulate 1,
4, 8, 16, 32, or 64 samples. After the defined number of samples have been accumulated, the result is
divided by either 1, 4, 8, 16, 32, or 64 (depending on the CS0ACU[2:0] setting) and copied to the
CS0DH:CS0DL SFRs.
