Because the count average requires a sum of at least two counts, not counting the maximum and minimum values, the set
number of times should be set to 4 or more.
(c) Moving average
Takes the average of digital output values sampled over a set number of sampling time intervals, and stores it
to the buffer memory.
Since the averaging processing is performed on a moving set of samples, the most current digital output values
can be obtained.
The moving average processing for a set number of times of 4 is shown below:
