AD8347's Gain Control

Hello everyone!

I am wondering what  AD8347's AGC mode is. Other words, if I want to control the gain by the external voltage (connecting VGIN pin to the external voltag) instead of internal circuit, what should I do with VAGC pin. Can I just leave it alone(float)? Or I must connect it to high or low level? Or it can be connected to the VGIN pin? The datasheet dosen't point out what shoule be done towards VAGC pin. 

Is there anyone who knows. I will appreciate your favor.

Thanks,thanks, and thanks again.
