3.4 Using ADCC’s Various Computation Modes

The ADCC module hardware contains post-conversion computation features, such as digital low-pass filtering/averaging and threshold comparison. The module can be configured to take additional samples or stop conversions, and an interrupt may be asserted based on computation results. These post-conversion computation features can be used to increase the signal-to-noise ratio in the sensor nodes by taking more samples of the signal and averaging or filtering them. The computation modes are described in detail below.
