LMK03001C register readback?

Hello,

I'm using the LMK03001C in a design and I'm a little confused.  The IO ports on the device are labeled as uWire.  The uWire spec (as I understand it) has both input and output capabilities (input is clocked on rising edges while outputs are clocked on falling edges).  The datasheet for the LMK device states that DATAuWire pin is for input.  There is no mention of an output.

So my question is: can we readback the registers from these devices?

Thanks
