PURPOSE:To improve the working efficiency of a program evaluating microcomputer by supplying the outputs of both a clock oscillating part and a clock dividing part connected to said oscillating part to a discriminating part and supplying either the divided clock frequency or the previous clock frequency to a program evaluating microcomputer. CONSTITUTION:The outputs of a clock oscillating part 10 and a clock dividing part 20 connected to the part 10 are supplied to a discriminating part 30. Then the control signals are sent to these parts 10, 20 and 30 from a clock control part 50, and the part 50 can indicate the division value of the part 20. Then the part 50 indicates the 1st action mode to the part 30. While the signal of the part 20 is sent to a program evaluating microcomputer 40 for execution of a user program. Then the 2nd action mode is indicated to the part 30 from the part 50, and the signal of the part 10 is sent to the computer 40 for execution of a system mode such as the setting of conditions. |
