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.

EEPROM Data In: This pin is driven by the
EEDO output of the external EEPROM.
EEPROM Data Out: This pin drives the EEDI
input of the external EEPROM.
Auto-MDIX Enable Configuration Strap:
Determines the default Auto-MDIX setting.
0 = Auto-MDIX is disabled.
1 = Auto-MDIX is enabled.
See
configuration straps.
EEPROM chip select: This pin drives the chip
select output of the external EEPROM.
EEPROM Clock: This pin drives the EEPROM
clock of the external EEPROM.
Power Select Configuration Strap: Determines
the default power setting when no EEPROM is
present.
0 = The LAN9500/LAN9500i is bus powered.
1 = The LAN9500/LAN9500i is self powered.
See
configuration straps.
JTAG Test Port Reset (Active-Low): In internal
PHY mode, this pin functions as the JTAG test
port reset input.
Receive Data 0: In external PHY mode, this pin
functions as the receive data 0 input from the
external PHY.
