EEPROM – store the initial value
IP113M LF supports two ways to load initial value of MII registers. The procedure is illustrated as below.
IP113M LF
1. IP113M LF reads the default setting of MII register from pins

2. IP113M LF updates the default setting of MII by reading EEPROM. If there exists an
EEPROM.

3. After reading EEPROM, IP113M LF is virtually isolated from the EEPROM. Micro-controller
can program both MII register and EEPROM.

4. IP113M LF reloads the content of EEPROM to recover the value in MII registers
programmed by Micro-controller after power on reset.
