The ’F402 expandable Serial Data Polynomial generator/  
checker is an expandable version of the ’F401. It provides  
an advanced tool for the implementation of the most widely  
used error detection scheme in serial digital handling sys-  
tems. A 4-bit control input selects one-of-six generator poly-  
nomials. The list of polynomials includes CRC-16, CRC-

applications. The Error output indicates whether or not a  
transmission error has occurred. The CWG Control input  
inhibits feedback during check word transmission. The
