Signal Name
NOTES:
1. ICH4 sets these signals at reset for processor frequency strap.
2. N/A for Mobile [GPIO[18] will toggle at a frequency of approximately 1 Hz when the ICH4 comes out of reset].
3. CPUPWRGD is an open-drain output that represents a logical AND of the ICH4’s VGATE / VRMPWRGD and
4. LAN Connect and EEPROM signals will either be “Defined” or “Off” in S3–S5 states depending upon whether
5. The state of the DPRSLPVR signal in S1-M is high if Deeper Sleep is enabled or low if it is disabled.
6. The states of main I/O signals are taken at the times during PCIRST# and Immediately after PCIRST#.
7. The states of resume I/O signals are taken at the times during RSMRST# and Immediately after RSMRST#.
8. SLP_5# is high in the S4 state and asserted low in the S5 state.
PWROK signals, and thus will be driven low by ICH4 when either VGATE / 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.
