AD7172-4 pull-ups on GPIO

Question

I would like to know if there are internal pull-ups or pull-downs on the GPIO pins on the AD7172-4. 
 The datasheet (rev B pg 42) says "All general-purpose outputs have an active pull-up." If I set GPIO0 and GPIO1 to inputs, will they still have pull-ups?

Hi, 
 There are no pull-up resistors when being used as inputs. 
 If they are being used as inputs then then pin should be driven to either AVDD1 or AVSS to avoid any increase in IDD current. 
 
 Thanks,
