How can I use only master part of A2B (AD2428W)?

Hi, everyone

I am creating new project with A2B interface. I choosed IC (AD2428W) for this interface.

IC (AD2428W) have master and slave parts of A2B interface. I need to use only master part of A2B interface. Slave part will not used. What do I need to do with pins of slave part (17, 18 and 19 pins)? They have to connect to GND or NC? I did not find this information on datasheet.



How can I use only slave part of A2B (AD2428W)?
