Fractional Voltage Controlled Multi TAP Delay ADAU1466

I'm quite new to AD DSP and have recently acquired a 1701 evaluation board and a 1466 Evaluation board. I'm trying to use the Fractual Voltage Controlled Multi Tap Delay, but I can't get my head around the control input (samples, percentage?) and  the data format to be used? I can't find anythig in the documentation.

I'm using the SIGMA Studio 3.16 Beta Version of the program.

I'm trying to control the delay time of six taps with one ADC.

Ant help is much appreciated

    Thanks for the quick response. Your example works on the 1466   I was using the Fractional Delay which requires an input between 0 -1 (8:24 numerical format) which changes the delay length from 0 - 100 %.

    I had to do a 14 bit << shift on the ADC output to get it working.

    Thanks again for your help. Quite to lot to take in for me, and it's good to know that there are people out there willing to help.
