Low until Intel High Definition Audio Controller Reset bit set (D27:F0:Offset
HDBAR+08h:bit 0), at which time ACZ_RST# will be High and ACZ_BIT_CLK will be
Running.

GPIO18 will toggle at a frequency of approximately 1 Hz when the ICH7 comes out of reset
13.
GPIO25 transitions from pulled high internally to actively driven within 100 ms of the
deassertion of the RSMRST# pin.

well as what device drives the signal at various times. Valid states include:
High

Static: Will be high or low, but will not change
Driven: Will be high or low, and is allowed to change
Running: For input clocks
ICH7 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# and
SLP_S5#. These signals are determinate and defined prior to RSMRST# deassertion.
ICH7 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.
