Description
voltage for analog voltage measurement.
CASEOPEN detection. An active low input
from an external device when chassis is
Intruded. This signal will be latched even the
chassis is closed.
Intel® CPU Vtt power.
It is also a voltage monitor channel.
Detect range is 0~2.048V
Intel® CPU PECI interface. (default)
System reset input. (default)
When this pin is asserted to low, Watch-dog
timer will be reset.
Fan tachometer input
This is a bi-directional pin.
As an input signal, when it is pulled to low, the
corresponding fan control output pins will be
set to a preset value.
System clock input. PECI and FAN functions
will use this clock to drive logics.

System Management Interrupt. (default)
Fan tachometer input
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.
Over temperature alert. Low active.
BEEP output when abnormal event occurs.
When this is no abnormal events, this pin
asserts high. (default)
