The terminal is to indicate the connection status of the upstream port as documented below: 0 = Hub not in SuperSpeed mode 1 = Hub in SuperSpeed mode Can be left unconnected. The value of the terminal is sampled at the de-assertion of reset to set the power switch control follows: 0 = Full power management supported 1 = Full Power management not supported When SMBus mode is enabled using SMBUSz, this terminal sets the value of the SMBus slave address bit 1. This terminal should be pulled up or down using an external resistor and should not be left unconnected.

3. 1
I2C EEPROM Operation
The TUSB8040 supports a single-master, standard mode (100 Kbit/s) connection to a dedicated I2C EEPROM when the I2C interface mode is enabled. In I2C mode, the TUSB8040 reads the contents of the EEPROM at bus address 1010000b using 7-bit addressing starting at address 0. If the value of the EEPROM contents at byte 00h equals 55h, the TUSB8040 loads the configuration registers according to the EEPROM map. If the first byte is not 55h, the TUSB8040 exits the I2C mode and continues execution with the default values in the configuration registers. The hub will not connect on the upstream port until the configuration is completed. The requirement for data in those addresses is dependent on the options configured in the Device Configuration and Phy Custom Configuration registers. For details on I2C operation refer to the UM10204 I2C-bus Specification and User Manual.
3. 2
SMBus Slave Operation
When the SMBus interface mode is enabled, the TUSB8040 supports read block and write block protocols as a slave-only SMBus device with a slave address of 1000 11xy, where · x is the state of FULLPWRMGMTz_SMBA1 at reset, and · y indicates read (logic 1) or write (logic 0) access. If the TUSB8040 is addressed by a host using an unsupported protocol it does not respond. The TUSB8040 waits indefinitely for configuration by the SMBus host and does not connect on the upstream port until the SMBus host indicates configuration is complete by clearing the CFG_ACTIVE bit. For details on SMBus requirements refer to the System Management Bus Specification.

Configuration Registers
The internal configuration registers are accessed on byte boundaries. The configuration register values are loaded with defaults but can be over-written when the TUSB8040 is in I2C or SMBus mode.

The first byte of the EEPROM is compared to the mask 55h and if not a match, the TUSB8040 aborts the EEPROM load and executes with the register defaults.
