//***************************************************************//
// Chien Search and Error Evaluator (CSEE) block find            //
// error location (Xi) while determine its error magnitude (Yi). //
// This CSEE block implement Chien search algorithm to find      //

// error value. Error value will be outputted serially and has   //
// to be synchronous with output of FIFO Register.               //
