Preliminary
Alarm beep output. Normal, this pin is low. When abnormal event
happens, this pin will output alarm frequency.
Internally connected to all analog circuitry. The ground reference for all
analog inputs.
0V to 4.096V FSR Analog Inputs.
This pin is power for W83791D. Bypass with the parallel combination of
10µF (electrolytic or tantalum) and 0.1µF (ceramic) bypass capacitors.
This pin is power for W83791D.
0V to 4.096V FSR Analog Inputs.

Reference voltage.
Thermistor 3 terminal input.(Default).
Pentium^TM II diode 3 input.
This multi-functional pin is programmable.
Thermistor 2 terminal input. (Default).
Pentium^TM II diode 2 input.
This multi-functional pin is programmable.
Thermistor 1 terminal input. (Default).
Pentium^TM II diode 1 input.
This multi-functional pin is programmable.
Voltage Supply readouts from CPU. After programming, this pin can be
VID output to voltage regulator to generate Vcore for CPU.
Over temperature Shutdown Output for temperature sensor 1-3.
Interrupt request.
General purpose I/O function. If pin 9 (SPEECH_SEL) is trapped to high
at VSB power on, this function will be active.
System Management Interrupt (open drain).
LED output control. This is a multi-function pin with SMI. When the
register (Bank0 Index 17h bit7 and Index A6h bit 6) is set to 1, LED
output function will be active. Otherwise, set to 0 (default), this pin
serves as SMI#.
Event trapping to selection speech output sound. Default is high edge
trigger.
General purpose I/O function. If pin 9 (SPEECH_SEL) is trapped to high
at VSB power on, this speech function will be active. The I/O control
and status is defined in BANK0 Index 13h~14h. Otherwise, GPIO pin or
FAN inputs can be selected by registers.
Event trapping to selection speech output sound.
