I will implement a new validation process in an protocol between two microcontrollers and I need an  unrepeatable number.  I suppose the Serial Number from chip is unrepeatable , so I suppose be a good way to solve this issue.

I read about this issue in this topic: https://www.lpcware.com/content/forum/read-serial-number but I don't found nothing about 22XX (Arm 7).

How can I obtain this number in 22XX family?
