1.1.6EEPROM Controller

The LAN9500/LAN9500i contains an EEPROM controller for connection to an external EEPROM. This allows for the automatic loading of static configuration data upon power-on reset, pin reset, or software reset. The EEPROM can be configured to load USB descriptors, USB device configuration, and MAC address.

1.1.7General Purpose I/O

When configured for internal PHY mode, up to eleven GPIOs are supported. All GPIOs can serve as remote wakeup events when the LAN9500/LAN9500i is in a suspended state.
