TPS56720 Question about I2C

Other Parts Discussed in Thread: TPS56720

Hi,

I have a question about I2C on TPS56720.

When I2C function is not used,  SCL and SDA should be "pull-down", and A0 and A1 should be "open".  Is it correct?

Best Regards,

    From the datasheet:

    "When only external regulation mode is used in a TPS56X20 application, the VOUT terminal should be tied to the

    output voltage of the converter and SDA & SCL terminals should be grounded. A0 & A1 terminals may be

    floating."
