SMBus or EEPROM interface behavior.
Reserved
Configured as an SMBus slave for external download of user-
defined descriptors. SMBus slave address is 0101100
Internal Default Configuration via strapping options.
2-wire (I2C) EEPROMS are supported,
(Serial Data)/(SMB Data) signal.
(Serial Clock)/(SMB Clock) signal. This multifunction pin is
read on the rising edge of RESET_N (see the applicable

24MHz crystal or external clock input.
This pin connects to either one terminal of the crystal or
to an external 24MHz clock when a crystal is not used.
24MHz Crystal
This is the other terminal of the crystal, or left
unconnected when an external clock source is used to
drive XTAL1/CLKIN. It must not be used to drive any
external circuitry other than the crystal circuit.
Clock In Enable:
Low = XTAL1 and XTAL2 pins configured for use with
external crystal
High = XTAL1 pin configured as CLKIN, and must be
driven by an external CMOS clock.
This active low signal is used by the system to reset the
chip. The minimum active low pulse is 1us.
Detects availability of local self-power source.
Low = Self/local power source is NOT available (i.e., Hub
gets all power from Upstream USB VBus).
High = Self/local power source is available.
Used for testing the chip. User must treat as a no-
connect or connect to ground.
