Configuration strap values are latched on power-on reset and system reset. Configuration
straps are identified by an underlined symbol name. Signals that function as configuration
straps must be augmented with an external resistor when connected to a load.

This pin is driven by the EEDO output of the
external EEPROM.
This pin drives the EEDI input of the external
EEPROM.
Determines the default Auto-MDIX setting.
0 = Auto-MDIX is disabled.
1 = Auto-MDIX is enabled.
See
configuration straps.
This pin drives the chip select output of the
external EEPROM.
Note:
This pin drives the EEPROM clock of the external
EEPROM.
Determines the default power setting when no
EEPROM is present.
0 = The device is bus powered.
1 = The device is self powered.
See
configuration straps.
Note 3.2
Note 3.2
The EECS output may tri-state briefly
during power-up. Some EEPROM
devices may be prone to false selection
during this time. When an EEPROM is
used, an external pull-down resistor is
recommended on this signal to prevent
false selection. Refer to your EEPROM
manufacturer’s datasheet for additional
information.
