DESCRIPTION
1
EEPROM
Data In
EEDI
IS
(PD)
This pin is driven by the EEDO output of the
external EEPROM.
1
EEPROM
EEDO
Data Out
O8
(PU)
This pin drives the EEDI input of the external
EEPROM.
Auto-MDIX
Enable
Configuration
Strap
AUTOMDIX_EN
IS
(PU)
Determines the default Auto-MDIX setting.
0 = Auto-MDIX is disabled.
1 = Auto-MDIX is enabled.
See Note 2.1 for more information on
configuration straps.
1
EEPROM
EECS
Chip Select
O8
This pin drives the chip select output of the
external EEPROM.
Note:
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.
1
EEPROM
EECLK
O8
This pin drives the EEPROM clock of the external
Clock
(PD)
EEPROM.
Note: This pin must be pulled-up externally for
proper operation.
Note 2.1
Configuration strap values are latched on Power-On Reset (POR) or External Chip Reset
(nRESET). Configuration straps are identified by an underlined symbol name. Pins that
function as configuration straps must be augmented with an external resistor when
connected to a load.
