Current Sinking of Refin/Out pin on AD7323

When you wish to select the enhanced input range of the AD7323, the data sheet states to apply +3V to the Refin/out pin.  Under absolute Max Ratings' it states that the maximum input current is 10mA, excluding the supplies. Does this pin then count as a ‘supply’? Also, I do not see a minimum current required for the pin in the data sheet. 

 

What is the max and min current that the Refin/out pin can sink when operated in normal mode and in full shutdown mode?

 

Below is the data sheet for the AD7323:
