Problem with PINx in Arduino DUE

Hi !

I have a question, about the istruction PINx about Arduino DUE.

I used this istruction with Arduino UNO and Arduino Nano and it is very useful, but now I want to use it with Arduino DUE for my project, so I searched how to use it, but I found that is difficult to use it with DUE, because the microcontroller is different from other platforms. Can someone help me ?
