Altering prescale values in Arduino due

Hi,

I want to know how can i alter/change prescale values in arduino due. I already tried and succeeded with Arduino UNO. And I am currently working on Arduino due and would like to know how can i do the same for Arduino Due.

Regards

Whic peripherals are you going to use?

I'm using Ct's to read real time AC current values. I did alter Prescale values of Arduino UNO before. I was just hoping that i could do the same with arduino due. My purpose is to further speed up the Analog read.
And sorry for replying so late.
