Abstract
PURPOSE:To generate an interrupting signal when an arbitrary address is executed only at the arbitrary number of times by detecting the coincidence of an execution address and an interruption address by a first comparing means, calculating the number of the times of coincidence with a counting means and detecting by a second comparing means that the counted value becomes the number of the times of interruption execution. CONSTITUTION:An interruption address is stored into a register 8 and the number of the times of interruption execution is stored into a register 10. The execution address and the interruption address are compared by a comparator 12 and at the time of coincidence, a coincident signal is outputted to a counter 14. By the coincident signal, the counter 14 counts up. When the counted value of the counter 14 is coincident with the number of the times of interruption execution, a comparator 16 outputs an interruption signal to an AND gate 18. Since an interruption permitting signal is inputted to the AND gate 18, the inputted interrupting signal is inputted to a control device 2 as it is. Thus, the control device 2 stops the execution of a microprogram.
