When using Differential mode, along with Auto Trigging from a source other than the ADC Con-
version Complete, each conversion will require 25 ADC clocks. This is because the ADC must
be disabled and re-enabled after every conversion.
In Free Running mode, a new conversion will be started immediately after the conversion com-
pletes, while ADSC remains high. For a summary of conversion times, see
