Section 14   CRC Operation Circuit (CRC) 

This LSI has a cyclic redundancy check (CRC) operation circuit to enhance the reliability of data 
transfer in high-speed communications, etc. The CRC operation circuit detects errors in data 
blocks.  

14.1 Features 

The features of the CRC operation circuit are listed below. 

• 

CRC code generated for any desired data length in an 8-bit unit 

• 

CRC operation executed on eight bits in parallel 

• 

One of three generating polynomials selectable 

• 

CRC code generation for LSB-first or MSB-first communication selectable 

 

Figure 14.1 is a block diagram of the CRC operation circuit.
