PURPOSE:To make units diagnose by themselves without data transfer among units by comparing a parity code, obtained from transmitted or received information through fixed arithmetic, with that of transmitted or received information. CONSTITUTION:In case of reception, a drive gate signal is [0]. For the purpose, information on pure data bit line BD and a parity bit on parity bit line Bp are inputted to parity-checker/generator 4 for a parity check. This result is sent to FF6 by way of multiplexer 5 and when a parity is detected, FF6 is set. |
