Xbee 868lp - How to obtain 2.3uA current consumption?

I’m working with a Xbee 868lp (XB8-DMUSB002-REVB)

I’m using CodeWarrior to write the code for my application.

What is the setup to obtain 2.3uA current consumption in sleep mode, as declared in datasheet and website secification section?

Thank you.

You need to set all unused GPIO lines as input and disable the internal pullup.
