TUSB1042I: Should the TEST1 pin be connected directly to ground, or left floating

According to the datasheet for the Tusb1042I the TEST1 pin should be connected directly to ground (page 4). However, if I look in the schematic for the evaluation board TUSB1042EVM (page 5), this pin appears to be floating. The functionality of the pin is not clearly stated, so I'm not sure which would be the correct solution here.

Hi Anders,

In the application TEST1 should be pulled-down to GND. In the EVM this pin is floating, since this configuration provides internal testing for TI.
