Preliminary Data Sheet
EEPROM – store the initial value
IP113F supports two ways to load initial value of MII registers. The procedure is illustrated as below.
IP113F
1. IP113F reads the default setting of MII register from pins

2. IP113F updates the default setting of MII by reading EEPROM. If there exists an EEPROM.

3. After reading EEPROM, IP113F is virtually isolated from the EEPROM. Micro-controller can
program both MII register and EEPROM.

4. IP113F reloads the content of EEPROM to recover the value in MII registers programmed
by Micro-controller after power on reset.
