DATASHEET
1.1.6 EEPROM 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.
1.1.7 General 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.
