PURPOSE:To confirm the internal state of a microcomputer for program evaluation in real-time execution through an external control circuit by allowing a writable/readable memory control part to confirm that a microcomputer for program control is in writing operation. CONSTITUTION:The writable/readable memory control part 15 reads internal information on the microcomputer 11 for program evaluation in real-time execution. At this time, the microcomputer has top priority when reading or writing data in or out of a writable/readable memory 14, and the memory control part 15 comes next. In this preferential operation, the memory control part 15 checks the state of a write enable line 3 from the microcomputer 11 to confirm whether the microcomputer 11 is in operation or not. The memory control part 15 has an operation device such as a keyboard for setting externally conditions. |
