Asynchronous signal CRS is asserted by the PHY when either the transmitted or
receive medium is non-idle.
Station Management Data Input /Output:
Serial data input/Output transfers from/to the PHY. The transfer protocol conforms
to the IEEE 802.3u MII specification.
Station Management Data Clock:
The timing reference for MDIO. All data transfers on MDIO are synchronized to the
rising edge of this clock.
Interrupt signal from PHY, active low.

A clock from Giga-PHY operates in MII mode.
If Giga-PHY provides clock for 10/100M in MII mode, AX88180 can use this pin as
reference clock. For normal operation, to connect TXCLK of Giga-PHY with this
pin.

Pin Description
Interrupt to host system
When the polarity is active high, this signal must be pulled low, otherwise pulled
high in active low environment. Software set the bit6 of command register (CMD) to
response the polarity.
Reset signal: active low.
Reference Clock. This clock may be from host (synchronous mode) or the output of
stand-alone OSC (asynchronous mode).
Wake-up signal to system. When the polarity of system is active high, this signal
must be pulled low, otherwise pulled high in active low environment. Software set
the bit0 of command register (CMD) to response the polarity.
