When programmed to do so, is
asserted when the LAN9118 detects
a wake event and is requesting the
system to wake up from the
associated sleep state. The polarity
and buffer type of this signal is
programmable.
Note:
Detection of a Power
Management Event, and
assertion of the PME signal
will not wakeup the
LAN9118. The LAN9118 will
only wake up when it
detects a host write cycle
(assertion of nCS and
nWR). Although any write to
the LAN9118, regardless of
the data written, will wake-
up the device when it is in a
power-saving mode, it is
required that the
BYTE_TEST register be
used for this purpose.

This signal functions as a
configuration input on power-up and
is used to select the default Ethernet
settings. Upon deassertion of reset,
the value of the input is latched. This
signal functions as shown in
Table 2.2, "Default Ethernet Settings",
below.
