The MC10E/100E193 is an error detection and correction (EDAC)
circuit. Modified Hamming parity codes are generated on an 8-bit word
according to the pattern shown in the logic symbol. The P5 output gives
the parity of the whole word. The word parity is also provided at the PGEN
pin, after Odd/Even parity control and gating with the BPAR input. This
output also feeds to a 1-bit shiftable register, for use as part of a scan ring.
Used in conjunction with 12-bit parity generators such as the E160, a
SECDED (single error correction, double error detection) error system
can be designed for a multiple of an 8-bit word.
