This multi-functional pin is programmable.
Thermistor 1 terminal input. (Default)
Pentium
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 can be selected by
registers.
