This pin may serve as the PME_MODE_SEL
input when PME mode of operation is in effect.

This General Purpose I/O pin is fully
programmable as either a push-pull output, an
open-drain output, or a Schmitt-triggered input.

This pin is driven by the EEDO output of the
external EEPROM.
This pin drives the EEDI input of the external
EEPROM.
This pin drives the chip select output of the
external EEPROM.
Note:
This pin drives the EEPROM clock of the external
EEPROM.

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.
