PIN Description (continued)

Pin no.

Label

Type

Description

174

EEDO

IPL

Data input of EEPROM

175

EEDI

IPL/O Data output of EEPROM

It is input during reset period. After reset, it is an output signal EEDI to read

EEPROM. After reading EEPROM, this pin becomes an output signal MRXD3, if

external MII port is enabled (MII_P0_EXT_EN=1); otherwise, it is an input signal.

176

177

EECS

EESK

IPL/O Chip select of EEPROM

It is input during reset period. After reset, it is an output signal EECS to read

EEPROM. After reading EEPROM, this pin becomes an input signal.

IPL/O Clock input of EEPROM

It is input during reset period. After reset, it is an output signal EESK to read

EEPROM. After reading EEPRM, this pin becomes an output signal MII_CLK, if

external MII port is enabled (MII_P0_EXT_EN=1); otherwise, it is an input signal.

Misc.

OSCI

25Mhz system clock.

A 25Mhz clock from oscillator is fed to this pin. The X2 pin should be left open in

this application.

Crystal pin

A 25Mhz crystal can be connected to OSCI and X2.

Reset

RESETB

It is low active. It must be hold for more than 1ms. It is Schmitt trigger input.
