2.10.1 Overview of the CRC calculation circuit usage
Cyclic Redundancy Check (CRC) is a method that compares CRC code formed from transmission data
by use of a polynomial generation with CRC check data so as to detect errors in transmission data. Using
the CRC calculation circuit allows generation of CRC code. A polynomial counter is used for the polyno-
mial generation of CRC_CCITT (X
