DESCRIPTION
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 P6. This value is read in the
VID/Fan Divisor Register.
Over temperature Shutdown Output.
Pin 45--47 mode selection.
0 = The 3 lowest order bits of ISA Address Bus.(Default, internal
pull-down 47K ohm)
1 = 7 bit I²C^TM address setting pin.(bit2 - bit0)
System Management Interrupt (open drain). This output is
enabled when Bit 1 in the Configuration Register is set to 1. The
default state is disabled.
The three lowest order bits of the 16-bit ISA Address Bus. A0
corresponds to the lowest order bit.
(Default, when ARDMSEL =0 or left open )
The hardware setting pin of 7 bit I²C^TM serial address bit2, bit1
and bit0 at CR[48h]. (When ARDMSEL =1)
Chip Select input from an external decoder which decodes high
order address bits on the ISA Address Bus. This is an active low
input.
