PURPOSE:To easily monitor the processing state in real time during the execution of the microcomputer processing without using a microcomputer development support system. CONSTITUTION:A microcomputer 1 sends information on starting processing 1 to be outputted when executing the first processing to a processing execution recognition circuit 1. A processing execution recognition circuit 2 outputs a level '1' based on the information on starting the processing 1, and continuously outputs the level '1' until receiving the information on ending the processing 1 to be outputted by a computer 1 after the first processing. Level '0' is outputted upon receiving information on ending the processing 1. A lamp 5 is turned on only during the level '1' receiving the latch output. When the microcomputer 1 executes the second processing, the latch is performed by a processing execution recognition circuit 4. When a lamp 6 is turned on and the third processing is executed, latch is performed by the processing execution recognition circuit 4 and a lamp 7 is turned on. |
