(1)If AUXFANOUT is programmed for PWM output (Bank0 Index 12h,bit0 is 0)
Bit 7-0: AUXFANOUT PWM Duty Cycle. The PWM duty cycle is equal to this eight-bit value, divided by
(2)If AUXFANOUT is programmed for DC output (Bank0 Index 12h,bit0 is 1)
Bit 7-2: AUXFANOUT voltage control. The output voltage is calculated according to this equation.
Bit 1-0: Reserved.
