AD9833 - disable output

I am working with the AD9833 and the basic functionality sketch works fine.

My question:
I am looking for a subrutine for "output disable".

I have really tried to locate this by support from Google - so far - no luck.

I hope to get a little help here.

There is no 'output disable' (hi-Z), but you can stop it.
see sleep modes

You can add an ouput buffer with 3-state functionalty?
