6.15 CRC Controller (CRC)

6.15.1 Overview

The Cyclic Redundancy Check (CRC) generator can perform CRC calculation with programmable
polynomial settings.

6.15.2 Features



Supports four common polynomials CRC-CCITT, CRC-8, CRC-16, and CRC-32



CRC-CCITT: X

+ X

+ 1



CRC-8: X

+ X

+ X + 1



CRC-16: X

+ X

+ 1



CRC-32: X

+ X

+ X + 1



Programmable seed value



Supports programmable order reverse setting for input data and CRC checksum



Supports programmable 1’s complement setting for input data and CRC checksum



Supports 8/16/32-bit of data width



8-bit write mode: 1-AHB clock cycle operation



16-bit write mode: 2-AHB clock cycle operation



32-bit write mode: 4-AHB clock cycle operation



Supports using PDMA to write data to perform CRC operation
