signals, as well as the state at various times. Within the table, the following terms are
used:
“High-Z”
“High”
“Low”
“Defined”
“Undefined”
“Driven”
“Running”
“Off”
“Input”
Note that the signal levels are the same in S4 and S5, except as noted.
ICH8 suspend well signal states are indeterminate and undefined and may glitch prior
to RSMRST# deassertion. This does not apply to LAN_RST#, SLP_S3#, SLP_S4#,
SLP_S5# and SLP_M#. These signals are determinate and defined prior to RSMRST#
deassertion.
ICH8 core well signal states are indeterminate and undefined and may glitch prior to
PWROK assertion. This does not apply to FERR# and THRMTRIP#. These signals are
determinate and defined prior to PWROK assertion.

Tri-state. ICH8 not driving the signal high or low.
ICH8 is driving the signal to a logic 1.
ICH8 is driving the signal to a logic 0.
Driven to a level that is defined by the function or external pull-
up/pull-down resistor (will be high or low).
ICH8 is driving the signal, but the value is indeterminate.
Will be high or low, will be allowed to change.
Clock is toggling or signal is transitioning because function not
stopping.
The power plane is off; ICH8 is not driving when configured as
an output or sampling when configured as an input.
ICH8 is sampling and signal state determined by external driver.
