6 TEST and CD Pins

The TEST and CD pins have changed from the TUSB211 to the TUSB216I. In the TUSB216I these pins are dual-function pins in the TUSB216I for the I2C interface. If the TUSB216I is not configured to use I2C, then there are no changes needed for these pins. TI recommends connecting the CD signal to a test point on the PCB. If the TUSB216I is configured to use I2C, the test pin acts as the I2C SDA pin and CD acts as the I2C SCL pin. Both SDA and SCL should have a 4.7-kΩ pullup to 1.8 V or 3.3 V for I2C mode to be enabled in the TUSB216I.
