NOTES:
1.
In S3_HOT, signal states are platform implementation specific, as some external components
and interfaces may be powered when the Intel^® ICH7 is in the S3_HOT state.
2.
LAN Connect and EEPROM signals will either be “Driven” or “Low” in S3–S5 states
depending upon whether or not the LAN power planes are active.
3.
These signals can be configured as outputs in GPIO mode.
