I2C Mode

When SDA and SCL are pulled high at reset, the TUSB2E11 is in I2C Mode, where the TUSB2E11 typically acts as an eUSB2 to USB repeater. The repeater can be further configured using the 1.8 V I2C interface accessible at J6. I2C configuration, however, is not required for the repeater to operate. Please note that GPIO0 must be pulled high for normal I2C repeater mode operation.
