GND should be provided for testing
purposes. For normal operation, resistor
should be No Stuff.
5 6 THERMTRIP# is a 1.05 V tolerant
signal and voltage translation logic may
be required.
Parallel termination resistor should be
placed near the ICH4-M or system
receiver.
Series resistor should be placed
between the receiver and termination
resistor. Series resistor should have no
stub when connecting to the
THERMTRIP# trace from the CPU.
See section 4.1.4.1.2 for more details.
