Abstract

PURPOSE: To secure a quick processing for the interruption given from each circuit and thus increase the processing efficiency by inhibiting transmission of the interruption signals via the acceptance signal of the interruption signal and then carrying out the interruption scanning even under the interruption prpcessing of the processor.
CONSTITUTION: The operation is stopped for scanning counter 4, which gives scanning to circuits 1 and 2 sequentially and then holds the circuit addresses, by reception of signals IPT1 and 2. Then the interruption signals are memorized in FF12 and 14 and also sent to the processor. Furthermore, gate 9 is opened via read signal RD showing the acceptance of the interruption signal from the processor, and thus the circuit address of counter 4 is transferred to the processor. At the same time, the transmission is inhibited via signal RD for signals IPT1 and 2, and as a result counter 4 is operated even under the interruption processing of the processor.
