Description
0V to +3.3V amplitude fan tachometer input.
(Default)
0V to +3.3V amplitude fan tachometer input.
Fan speed control pin.
This pin is either PWM-duty mode or Linear mode.
Address power on trapping pin. Internal pull down100k ohm. The
internal pull-down resistor will be turn-off after power-on trapping.
(Default) General purpose I/O pin.
Fan speed control pin.
This pin is either PWM-duty mode or Linear mode.
