should be left unconnected.
External 25MHz Crystal output.
Active-low reset input. Resets all logic and
registers within the LAN9211. This signal is
pulled high with a weak internal pull-up resistor.
Note:
When programmed to do so, is asserted when
the LAN9211 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.
The LAN9211 must be reset on power-
up via nRESET or following power-up
via a soft reset (SRST). The LAN9211
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 46
Detection of a Power Management
Event, and assertion of the PME
signal will not wakeup the LAN9211.
The LAN9211will only wake up when it
detects a host write cycle (assertion of
nCS and nWR). Although any write to
the LAN9211, 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.
