The states of Vcc3_3 signals are taken at the times during PLTRST# and Immediately after
PLTRST#.
The states of VccSus3_3 signals are taken at the times during RSMRST# and Immediately
after RSMRST#.

and interfaces may be powered when the Intel
PETp/n[6:1] high until port is enabled by software.
LAN Connect and EEPROM signals will either be “Defined” or “Off” in S3–S5 states
depending upon whether or not the LAN power planes are active.
SLP_S5# signals will be high in the S4 state.
The state of the DPRSLPVR and DPRSTP# signals in C4 are high if Deeper Sleep is enabled
or low if it is disabled.
ICH7 drives these signals High after the processor Reset.
CPUPWRGD is an output that represents a logical AND of the Intel
and PWROK signals, and thus will be driven low by ICH7 when either VRMPWRGD or
PWROK are inactive. During boot, or during a hard reset with power cycling, CPUPWRGD
will be expected to transition from low to High.
IICH7 drives these signals Low before PWROK rising and Low after the processor Reset.
