W83637HF
Set 10, FANPWM1 is as Fan Speed Cruise Mode.
Set 11, reserved and no function.
Bit 1: FANPWM2 output mode selection. Set to 0, FANPWM2 pin is as output pin so that it can drive
a logical high or low signal. Set to 1, FANPWM2 pin is as open-drain pin which can only drive a
logical low signal.
Bit 0: FANPWM1 output mode selection. Set to 0, FANPWM1 pin is as output pin so that it can drive
a logical high or low signal. Set to 1, FANPWM1 pin is as open-drain pin which can only drive a
logical low signal.
