BQ27520-G4: What to do with TS pin when using internal temperature sensor

Part Number: BQ27520-G4


I'm working with BQ27520 Gas Gauge in my latest design. Battery used does not have an internal thermistor, I'm using external one connected to the charger IC, located very close to the Gas Gauge. To reduce footprint I configured Bq27520 to use internal temperature sensor - this leaves TS pin unused. I couldn't find any information about handling unused pins. Can I leave it floating? What's the recommendation?
