TMDS181: Address pin (A1) at Pin Strapping mode when EQ_SEL/A0 set to no connect

Part Number: TMDS181

If we use pin strapping, I understand we can still do I2C reads.  But if we set EQ_SEL/A0 to no connect for adaptive eq, what is the state of A0 for the I2C address?  Because we are not pulling up or down EQ_SEL/A0, I was not sure if A0 is not deterministic where it could be unstable in I2C reads (sometimes a low and sometimes a high).
