13.5. 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 con-
verted to a 16-bit value by dividing the 22-bit accumulator by either 1, 4, 8, 16, 32, or 64 (depending on the
CS0ACU[2:0] setting) and copied to the CS0DH:CS0DL SFRs.
