When programmed to do so, is
asserted when the LAN9218i 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:
Enables Auto-MDIX. Pull high enable
Auto-MDIX, pull low or leave
unconnected to disable Auto-MDIX.
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
below.
No Connect. These pins must be left
open.
Reserved for internal test purposes
only. This pin should be pulled low
through an external pull-down
resistor.
Detection of a Power
Management Event, and
assertion of the PME signal
will not wakeup the
LAN9218i. The LAN9218i
will only wake up when it
detects a host write cycle
(assertion of nCS and
nWR). Although any write to
the LAN9218i, 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.
