Interrupt request.
System Management Interrupt (open drain).
Over temperature Shutdown Output for temperature
sensor 1-3.
Fan speed control PWM/DC output. When the power
of VDD is 0v, this pin will drive logic 0. The power of
this pin is supplied by VSB 5V.
After programming, this pin can be GPIO.
0V to +5V amplitude fan tachometer input
After programming, this pin can be GPIO.
Fan speed control PWM output. When the power of
VDD is 0v, this pin will drive logic 0. The power of this
pin is supplied by VSB 5V.
After programming, this pin can be GPIO.
0V to +5V amplitude fan tachometer input
After programming, this pin can be GPIO.
Fan speed control PWM output. By default it’s high.
The power of this pin is supplied by VSB 5V.
Low active System RESET. If triggered, this pin will
send out 100ms low pulse for system reset.
0V to +5V amplitude fan tachometer input
System reset input, used to control WDT.
