Moving average
The A/D converter module averages digital output values taken at every sampling cycle for a specified number of times, and
stores a mean value in the buffer memory. Since the averaging processing is performed on a moving set of sampling, the
latest digital output values can be obtained.
The following figure shows the moving average processing of when the set number of times is five.
