ADV7513_I2C address Setting

Dear Sir,

We would like to use I2C address "7A" of ADV7513.

But our system is unstable I2C address. Sometimes it become I2C address "72".

Our sequence and condition.

PD/AD pin :Pull High 3.3V -> power on ADV7513 -> wait 200mese -> communicate with ADV7513 via I2C.

We refered "ADV7513_Hardware_User_Guide.pdf", section 6.6.1.

Maybe our sequence is no problem.

Please advise us what other point we check about I2C address setting.
