EEPROM – Chip Select. Tri-State during device reset.
Clock signal to EEPROM. Tri-State during device reset. When not in
reset, this outputs the EEPROM clock.
EEPROM – Data I/O. Connect directly to Data-in of the EEPROM and to
Data-out of the EEPROM via a 2.2K resistor. Also, pull Data-Out of the
EEPROM to VCCD via a 10K resistor for correct operation. Tri-State
during device reset.

Configurable Output Pin, the default configuration is Transmit
Asynchronous Data Output.
Configurable Input Pin, the default configuration is Receiving
Asynchronous Data Input.
Configurable Output Pin, the default configuration is Request to Send
Control Output / Handshake Signal.
Configurable Input Pin, the default configuration is Clear To Send Control
Input / Handshake Signal.
Configurable Output Pin, the default configuration is Data Terminal Ready
Control Output / Handshake Signal.
Configurable Input Pin, the default configuration is Data Set Ready
Control Input / Handshake Signal.
Configurable Input Pin, the default configuration is Data Carrier Detect
Control Input.
Configurable Input Pin, the default configuration is Ring Indicator Control
Input. When remote wake up is enabled in the EEPROM taking RI# low
can be used to resume the PC USB host controller from suspend. (Also
see note 1, 2, 3 in section 4.12)
