PURPOSE:To attain the accurate interruption of execution of a program by comparing the prescribed setting conditions with the signal on an internal bus and producing the control signal corresponding to the setting conditions according to the output signal of said comparison. CONSTITUTION:The internal address, internal data and internal control buses 12-14 are connected to a microprocessor part 11 consisting of a control part and an executing unit. Then break condition setting data registers 16a-16c and a control register 17 are connected to the buses 12 and 13 respectively. The data of registers 16a-16c are applied to the reference input side terminals of comparators 18a-18c. While the signals of buses 12-14 are applied to the comparison input side terminals respectively. The output of comparators 18a-18c are supplied to gate circuits 19a-19c which are controlled by the output of the register 17. Then output signals of those comparators are also supplied to a signalproducing circuit 21 via an OR gate circuit 20. The produced interruption signal IQ is supplied to the processor part 11. |
