PURPOSE: To specify a brake point in the brake function of an incircuit emulator by an optional bus cycle. CONSTITUTION: During the execution of a user program in a CPU 1, an address signal group 101, a status signal group 102 and a data signal group 103 are inputted from the CPU 1 through an input device 3 and comparators 4, 5 respectively compare the inputted signal groups with a previously set brake point and respectively output a comapared result 109 for the signal groups other than the data signal group 103 and a compared result 110 of the data signal group 103. A comparison judging device 6 judges whether the compared result 110 of the data signal group 103 is to be included in the compared result 109 or not in each bus cycle and an output switch 9 switches the output system of the compared result 109 in accordance with a judged result 108. An integrator 8 integrates a compared result 111 and the compared result 110 and an output device 9 outputs a compared result 112 and an integrated compared result 113 to the CPU 1 as a brake request signal 114 at different timing. |
