/**
* Analog Module class.
* Each module can independently sample its channels at a configurable rate.
* There is a 64-bit hardware accumulator associated with channel 1 on each module.
* The accumulator is attached to the output of the oversample and average engine so that the center
* value can be specified in higher resolution resulting in less error.
