FanStopTime – control the FANCTL1-FANCTL8 fan stop time from FONV (Fan Output
Nonstop Value) to the off state.
Unit in 0.1sec. Ranges from 0.1sec to 25.5sec.
If set to 0, the fan will never stop.
FANCTL3-FANCTL8 functions are not for W83795ADG.
F8POL – F1POL: control FANCTL8 - FANCTL1 PWM output polarity.
0 = Low active. PWM is controlled by negative duty cycle.
1 = High active. (Default). PWM is controlled by positive duty cycle.
FANCTL3-FANCTL8 functions are not for W83795ADG.
