Bypass VDD to VSS with a 0.1FF capacitor. 10 RS-1 Ground Reference for ADC1 Voltage Measurement 11 RS+2 Power-Supply ADC Voltage-Sense Input, Measurement Relative to RS-2 12 RS-2 Ground Reference for ADC2 Voltage Measurement 13 RST Reset Active-Low Input 14 MSDA Master I2C Data Input/Output. Open-drain output. 15 MSCL Master I2C Clock Output. Open-drain output. 16 PWM5 Fan PWM Output #5. CMOS push-pull output. Low when the fan is disabled. A 100% duty cycle implies this pin is continuously high. 17 TACH5 Fan Tachometer Input 18 PWM4 PWM Margin Output #4. High impedance when the margining is disabled. A 100% duty cycle implies this pin is continuously high. 19 PSEN4 Power-Supply Enable Output #4. Programmable through MFR_MODE for either active high or active low and either open drain or CMOS push-pull.
