even when AD conversion is still in progress. In repeat conversion modes (e.g., in
cases c and d), when the halt is released, conversion restarts from the beginning.
In single conversion modes (e.g., in cases a and b), conversion does not restart
when the halt is released (The converter remains stopped).
