Abstract

PURPOSE:To shorten the down time, by starting a count by the output of a parity check circuit and by stopping the count simultaneously with the stop of clocks, in the error processing device which checks an error with the parity check system. CONSTITUTION:If error data occurs in a B register 20 out of registers forming a loop, a check FF21 is lit by a check circuit 22, and a check counter 25 starts counting. Meanwhile, error data which occurred in the B register 20 lights check FFs 31 and 11 till the stop of clocks after 3 cycles and starts counting of check counters 35 and 15. When clocks stop after 3 cycles by the check of the B register, check FFs 11, 21 and 31 are lit and contents of counters 25, 35 and 15 hold 3, 2 and 1. Consequently, the FF for a maximum counter number is indicated as the check FF, which was lit first, to estimate a defective package.
