The MC66540 uses a modified Hamming code to generate six syndrome bits and six check bits to per- form Single Error Correction and Double Error Detection (SECKIED) on a data pattern of 16 bits. Two such devices can be used in tandem to generate the seven syndromes and check bits necessary to do error detection and correction on 32 data bits. The parts are able to operate in parallel by passing partial syn- dromes between them.
