SYSFANOUT Stop Value
When at Thermal Cruise mode, SYSFANOUT value will decrease to this value. This register should be
written a non-zero minimum stop value.
Please note that Stop Value does not mean that fan really stops. It means that if the temperature
keeps below low temperature limit, then the fan speed keeps on decreasing until reaching a minimam
value, and this is Stop Value.
