PURPOSE:To enable debug operation easily, by monitoring the content of the accumulator registor which is sequentially renewed and changed accompanied with the execution of instruction words with the operation setting the step of instruction words. CONSTITUTION:CPU2 is constituted with the firmware of itself, and the program stored in it is sequentially executed. Further, the content of the accumulator register R sequentially renewed and changed accompanied with the execution is transferred to the latch register LCR in the output port 5 for temporary storage. The output of the register LCR is linked with the least significant digit 61 of the display device 6, and the result of operation of the step 01 is displayed as ''1'' or ''0'' on the display device. Thus, the user confirms the content of display of the display device 61 and monitors the result of operation of the step 01. |
