> The 5VDD and 5VSB limit conversion subtracts the voltage offset from an
> unsigned value. A requested limit below the offset wraps and is clamped
> to 255. For example, writing zero to in7_min selects the highest limit
> instead of the lowest.
>
> Limit the subtraction to the converted input so that values below the
> offset select register zero.
