Table 3-3. Power Plane and States for Output and I/O Signals for Desktop Configurations
(Sheet 4 of 4)
NOTES:
10.GPO[18] will toggle at a frequency of approximately 1 Hz when the ICH6 comes out of reset
11.GPIO[25] transitions from pulled high internally to actively driven following the de-assertion of the RSMRST#
Signal Name
1. The states of Vcc3_3 signals are taken at the times During PLTRST# and Immediately after PLTRST#.
2. The states of VccSus3_3 signals are taken at the times During RSMRST# and Immediately after RSMRST#.
3. In S3
4. PETp/n[4:1] high until port is enabled by software.
5. SLP_S5# signals will be high in the S4 state.
6. ICH6 drives these signals Low before PWROK rising and High after the processor reset
7. CPUPWRGD is an open-drain output that represents a logical AND of the ICH6’s VRMPWRGD and PWROK
8. ICH6 drives these signals Low before PWROK rising and Low after the processor reset.
9. Low until Intel High Definition Audio Controller Reset bit set (D27:F0:Offset HDBAR+08h:bit 0), at which time

may be powered when the ICH6 is in the S3
signals, and thus will be driven low by ICH6 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-Z.
ACZ_RST# will be High and ACZ_BIT_CLK will be Running.
