Bit 7-0: AUXFANOUT PWM Duty Cycle. Write FFh, AUXFANOUT duty cycle is 100%. Write 00h,
AUXFANOUT duty cycle is 0%.
Note. XXh: PWM Duty Cycle output percentage is (XX/256*100%) during one cycle.
(2)If AUXFANOUT be programmed as DC Voltage output (Bank0 Index 12h.bit0 is 1)
Bit 7-2: AUXFANOUT voltage control.
Bit 1-0: 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).
