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.
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.
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.

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