24-MHz Crystal IN or External Clock Input.
24-MHz Crystal OUT. (NC if external clock is used)
Active LOW Reset. This pin resets the entire chip. It is normally tied to
V
other special power up procedure is required.
Self Power. Indicator for bus or self powered. 0 is bus powered, 1 is self
powered.
VBUS. Connect to the VBUS pin of the upstream connector. This signal
indicates to the hub that it is in a connected state, and may enable the
D+ pull up resistor to indicate a connection. (The hub does so after the
external EEPROM is read).
SPI Chip Select. Connect to CS pin of the EEPROM.
SPI Clock. Connect to EEPROM SCK pin.
SPI Dataline Connect to GND with 15 KΩ resistor and to the Data I/O
pin of the EEPROM.
