See CRC-CCITT -- 16-bit ( other source ) which explains it. It has to do with the question of "augmented" zero bits at the end of the message, and an algorithm that can avoid the need for it, but needs a modification to the initial value. mayeaux building products https://odlin-peftibay.com

WebAnother popular CRC algorithm is CRC-16-CCITT. This algorithm is primarily used in communication CRCs. The check value can be used in Class B applications by running an initial CRC then periodically running a CRC to confirm that the check value has not changed. 1.2 CRC Implementation There are a few common ways to implement a CRC.
