Abstract

PURPOSE: To ensure a quick operation at the interruption process part by masking the interruption request with every detection of the interruption request as well as the interruption request featuring the high priority and processing the interruption request featuring the low priority after the higher priority interruption request.
CONSTITUTION: Interruption masking circuit 11 is provided to receive interruption request signals I0WI7 and to inhibit the detection of the specified interruption request among signals I0WI7 via mask signals M1WM8 of mask information generator circuit 14, along with interruption priority circuit 12 to detect the interruption reguest accepted at circuit 11 based on the predetermined priority and then to transmit the detected interruption signal to interruption process part 3. Furthermore, the following two units are provided: interruption register 13 to supply interruption codes C1WC3 showing the types of the interruption request plus the detection signal of circuit 12 and to set codes C1WC3 via the process enable signal S sent from part 3; and mask information generator circuit 14 to produce signals M1W M8 which masks the higher priority interruption request according to codes C1W C3 of register 13.
