Must be connected to ground through

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.
