EEPROM
Data In
EEDI VIS
(PD)
This pin is driven by the EEDO output of the
external EEPROM.
1
EEPROM
Data Out
EEDO VO8 This pin drives the EEDI input of the external
EEPROM.
1
EEPROM
Chip Select
EECS VO8 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.

EEPROM
Clock
EECLK VO8 This pin drives the EEPROM clock of the external
EEPROM.
