TPS65132: I2C communication

Part Number: TPS65132

Hi team,

My customer is considering to use the TPS65132W with +/-5.4V output. Could you please advise for the questions below?

(1) When using the default setting voltage value of ±5.4V, is I2C communication unnecessary?

(2) If I2C communication is not required, is it OK to leave the SCL and SDA pins unconnected(floating)?
