Select

PME_MODE_SEL

VIS

(PU)

This pin may serve as the PME_MODE_SEL

input when PME mode of operation is in effect.

Refer to Chapter 4, "PME Operation," on page 30

for additional information.

DESCRIPTION

EEPROM

Data In

EEDI

VIS

(PD)

This pin is driven by the EEDO output of the

external EEPROM.

EEPROM

Data Out

EEDO

VO8

This pin drives the EEDI input of the external

EEPROM.

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.
