Description
IPL2
MII port enable
1: enable MII port,
0: disable MII port
This pin53 also determines the regulator output voltage. Please
see pin 52 REG_OUT for detail information.
MII mode selection
It is latched as MII MAC/ PHY mode selection at the end of
reset. It should be pull high if pin 72 RMII_MII is pulled high.
1: MAC mode,
0: PHY mode
After reset, it is used as clock pin SCL of EEPROM
MII RMII selection
It is latched as RMII_MII selection at the end of reset. It is valid
only if pin 53 EXTMII_EN is pulled high. Pin 104 MII_MAC
should be pull high RMII is enabled.
1: RMII,
0:MII
After reset, it is used as SPPED_LED1.

The external MAC device uses the interface to access the
registers of IP178C. IP178C doesn’t access the MII registers of
external PHY.
