The signals are arranged in functional groups according to their associated interface. The “N” symbol in the signal name indicates that the active, or asserted, state occurs when the signal is at a low voltage level. When “N” is not present before the signal name, the signal is asserted when at the high voltage level. The terms assertion

USB 2.0 High-Speed 4-Port Hub Controller Datasheet 4.3 EEPROM Interface The SMSC Hub can be configured via a 2-wire (I2C) EEPROM (256x8). (Please see Table 3.1 for specific details on how to enable configuration via an I2C EEPROM). The Internal state-machine will (when configured for EEPROM support) read the external EEPROM for configuration data. The hub will then “attach” to the upstream USB host. Note: The Hub does not have the capacity to write, or “Program,” an external EEPROM. The Hub on
