AD9985A: Disable Three-state data outputs

I'd like to find out if there is some way to disable/Three-state the data
outputs of the AD9985A device. the data sheet stated these are Three-state
outputs, yet i didn't find any configuration register to disable them.
disabling these outputs is important as I'd like to connect the AD9985A device
on a bus with other components.

 

The AD9985A is able to tri-state its outputs if you place it in power-down
mode.  This can be done by writing a '0' to R0x0F[1].  The serial bus is still
'alive' and non of the register settings have been lost, but the outputs are in
a tri-state mode.
