External 25MHz Crystal Input. This pin can also
be connected to single-ended TTL oscillator
(CLKIN). If this method is implemented, XTAL2
should be left unconnected.
External 25MHz Crystal output.
Active-low reset input. Resets all logic and
registers within the LAN9220. This signal is
pulled high with a weak internal pull-up resistor.
Note:
Note:
When programmed to do so, is asserted when
the LAN9220 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 or leave
unconnected to enable Auto-MDIX, pull low to
disable Auto-MDIX.
Note:
The LAN9220 must be reset on
power-up via nRESET or following
power-up via a soft reset (SRST). The
LAN9220 must always be read at least
once after reset, or upon return from a
power-saving state or write operations
will not function. See
"Detailed Reset Description," on
page 47
When operating at reduced
VDDVARIO voltage levels (less than
3.0V), this pin must be pulled-high to
a valid level with an external resistor
or must be driven as an input. Refer to
Section 2.2, "External Pull-Up/Pull-
Down Resistors"
Detection of a Power Management
Event, and assertion of the PME
signal will not wakeup the LAN9220.
The LAN9220will only wake up when it
detects a host write cycle (assertion of
nCS and nWR). Although any write to
the LAN9220, 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.
When operating at reduced
VDDVARIO voltage levels (less than
3.0V), this pin must be pulled to a valid
level with an external resistor. Refer to
Section 2.2, "External Pull-Up/Pull-
Down Resistors"
