8.11.2.13 Fan Output Nonstop Duty Cycle Register(FanNonStop)
Due to bring a fan from stop to work might take some time. The design of FanNonStop is hope to have
a minimum duty cycle to keep the fan rotating when system does not require fan help getting ride of
heat but still want to keep the fast response time to speed up fan. (Reference to Graph)

8.11.2.14 Fan Output Start Duty Cycle Register(FanStart)
From still to rotate, Fan usually needs a higher duty cycle to generate enough torque to conquer the
restriction force. Thus W83793G include a FanStart to bring the Fan live with the duty specified.
