Note: The pin names for the twisted pair pins shown above apply to a normal connection. If HP Auto-
MDIX is enabled and a reverse connection is detected, or a reverse connection is manually
selected, the input pins become outputs, and vice-versa, as indicated in the descriptions.

EEPROM Data: This bi-directional pin can be
connected to a serial EEPROM DIO. This is
optional.
General Purpose Output 3: This pin can also
function as a general purpose output, or it can
be configured to monitor the TX_EN or
TX_CLK signals on the internal MII port. When
configured as a GPO signal, or as a
TX_EN/TX_CLK monitor, the EECS pin is
deasserted so as to never unintentionally
access the serial EEPROM. This signal cannot
function as a general-purpose input.

EEPROM Clock: Serial EEPROM Clock pin.
General Purpose Output 4: This pin can also
function as a general-purpose output, or it can
be configured to monitor the RX_DV or
RX_CLK signals on the internal MII port. When
configured as a GPO signal, or as an
RX_DV/RX_CLK monitor, the EECS pin is
deasserted so as to never unintentionally
access the serial EEPROM. This signal cannot
function as a general-purpose input.
Note:
When the EEPROM interface is not
used, the EECLK pin must be left
unconnected.
