Gigabit Ethernet Controller Wake: This active
low signal is used by the GbE’s to signal that a
PME event has occurred. It is the wired OR of
all three Gigabit Ethernet Controllers on the
EP80579 .
Gigabit Ethernet Controller: This is the
PWR_GOOD signal used by GbEs supplied by
primary core power. This signal indicates that
all chip power supplies are on and stable. This
signal should be asserted once core power is
stable.
Gigabit Ethernet Controller Power Good: Input
signifying that the GbE Port 0 and
miscellaneous support IO power supplies are
on and stable (this is the PWR_GOOD signal
which is pinned out for GbE Port 0 only). When
an auxiliary power supply is used for GbE Port
0, this signal should be asserted once that
auxiliary power is stable. If Core power is used
for GbE Port 0 then this pin should be tied to
the core Power OK signal SYS_PWR_OK.
