Master I
Fan PWM Output #5. CMOS push-pull output. Low when the fan is disabled. A 100% duty cycle
implies this pin is continuously high.
Fan Tachometer Input
PWM Margin Output #4. High impedance when the margining is disabled. A 100% duty cycle implies
this pin is continuously high.
Power-Supply Enable Output #4. Programmable through MFR_MODE for either active high or active
low and either open drain or CMOS push-pull.
