The scope of this article is to describe the basic concepts related to CRC (Cyclic Redundancy Check), an efficient and widely used way to protect data against accidental corruption.

In a previous article we have seen the basic concepts related to the CRC (Cyclic Redundancy Check) calculation and its importance in providing a protection against accidental data corruption. Scope of this article is to show how those concepts have been applied on a commercial microcontroller family: the Flexis AC by Freescale.
