0V to +3.3V amplitude fan tachometer input.
General purpose I/O pin. Default Open drain
Use PWM duty cycle to control fan3 speed.
Use linear voltage output (0~3.3V) to control fan3 speed.
General purpose I/O pin. Default Open drain
0V to +3.3V amplitude fan tachometer input.
General purpose I/O pin. Default Open drain
Use PWM duty cycle to control fan2 speed.
Use linear voltage output (0~3.3V) to control fan2 speed.
General purpose I/O pin. Default Open drain
0V to +3.3V amplitude fan tachometer input.
Use PWM duty cycle to control fan1 speed.
Use linear voltage output (0~3.3V) to control fan1 speed.
System management interrupt (Pure open drain). This pin will be
active low when there is something wrong with voltage, temperature
and fan. See register description index 33h
