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.
Data Bus Width Select: This signal also
functions as a configuration input on power-up
and is used to select the host bus data width.
Upon deassertion of reset, the value of the
input is latched. When high, a 32-bit data bus
is utilized. When low, a 16-bit interface is
utilized.

EEPROM Clock: Serial EEPROM Clock pin.
