ADV7181C - Chip I2C Address

We are working on ADV7181C and we have problems about its i2c address.

First, we connect ALSB pin to 3V3. But the i2c address is 0x21. I read "ADV7181C_Manual_RevC.pdf". According to this documentation, chip address is 0x21 when ALSB bit is low. 

So how can we configure ADV7181C chip address correctly ? 

Thanks for answers.
