Abstract

PURPOSE:To easily search the cause for the occurrence of failure by storing the information transmitted in every occurrence of failure. CONSTITUTION:If there is any error in information transmission S1-SN, this is detected by a parity detector 13, and a parity check signal PK is generated from a pulse generator 14 in every incoming of a system clock CL, and the information having the error is written in a memory circuit 15. The information read out from the memory circuit 15 is processed for display and storage in an output processing circuit as required, for the searching the cause for the occurrence of the parity error.
