TVP5150 I2C

Other Parts Discussed in Thread: TVP5150AM1

I have a customer asking for clarification on the following:

Can you tell me exactly when the TVP5150AM1 determines its I2C address?   The datasheet indicates at power up, but what is power up defined as?  Elsewhere in the datasheet it says that the register values are retained when the power down pin is driven low, so does this mean the registers are maintained, but the I2C address can change?

    The I2C address selection (YOUT7_I2CSEL pin) is sampled only during RESETB.  PDN will have no impact on the I2C address.
