AD5410 daisy chain and DCEN bit


I've read several questions about the AD5410 already and also checked the datasheet.

What I don't really understand is how I get this "DCEN" bit set on all devices in the first place.

If I understand correctly, then the SDO pin only outputs the bits for the next chip if DCEN is set.

So how does my initialization sequence look like? How do I get the DCEN bit set in the second IC? Can I send 24xN bits right from the start to get all chips DCEN set or do I have to trick somehow? Maybe by sending one control register sequence at first, then send it twice, then threefold, ... until I finally have all chips in daisy chain mode?

Thanks in advance
