Description
This pin is related to ASF commands.
This is a bi-directional pin.
As an input signal, when it is pull-ed to low, the
corresponding fan control output pins will be
set to a preset value.
Output signal for system reset. (default)
There are two reset sources: Watch-dog timer
and ASF RESET command. When reset event
occurs, this pin will assert 100ms low pulse for
system reset.
This is a bi-directional pin.
As an input signal, when it is pull-ed to low, the
corresponding fan control output pins will be
set to a preset value.
Fan tachometer input
Fan speed control PWM/DC output. When the
power of 3VDD is 0V, this pin will drive logic 0.
The power of this pin is supplied by 3VSB.
It can be configured to PWM/DC mode by
registers. Default is PWM output.
As DC output, 256 steps output voltage scaled
to 0~3VSB.
