The Vlogic pin of the AD5316R is not working

When the AD5316R is connected to VDD=5V, a voltage of 4.25V is automatically generated on the Vlogic. While the I2C pull-up voltage I want to use is 3.3V, Vlogic cannot connect the digital voltage of 3.3V externally, because it will raise 3.3V on the microcontroller power supply.Does the Vlogic have to be supplyed? Will floating affect IC working? If I have to access it, how do I do it?
