Reserved
Bit 7: Reserved
Bit 6: Set 1, CPUFANOUT1 value will decrease to and keep the value set in Index 64h when
temperature goes below target range. This is to maintain the fan speed in a minimum value.
Set 0, CPUFANOUT1 value will decrease to 0 when temperature goes below target range.
Bit 5: Set 1, SYSFANOUT value will decrease to and keep the value set in Index 08h when
temperature goes below target range. This is to maintain the fan speed in a minimum value.
Set 0, SYSFANOUT value will decrease to 0 when temperature goes below target range.
Bit 4: Set 1, CPUFANOUT0 value will decrease to and keep the value set in Index 09h when
temperature goes below target range. This is to maintain the fan speed in a minimum value.
Set 0, CPUFANOUT0 value will decrease to 0 when temperature goes below target range.
Bit 3: Set 1, AUXFANOUT value will decrease to and keep the value set in Index 17h when
temperature goes below target range. This is to maintain the fan speed in a minimum value.
Set 0, AUXFANOUT value will decrease to 0 when temperature goes below target range.
Bit 2-1: AUXFANOUT mode control.
Set 00, AUXFANOUT is as Manual Mode. (Default).
Set 01, AUXFANOUT is as Thermal Cruise Mode.
Set 10, AUXFANOUT is as Fan Speed Cruise Mode.
Set 11, reserved and no function.
Bit 0: AUXFANOUT output mode selection. Set to 0, AUXFANOUT pin is as PWM output duty cycle
so that it can drive a logical high or low signal. Set to 1, AUXFANOUT pin is as DC voltage output
which can provide analog voltage output. (Default 0)
