<p>PURPOSE: To monitor the processing speed and processing order of its own microcomputer without using the microcomputer on an outside. CONSTITUTION: By an interval timer 25, the prescribed number of reference clocks RCK are counted and interruption request signals 30 are supplied to a microprocessor 21 at each stipulated cycle (1ms, for instance.) By an event counter 41, clocks CCK for comparison counting are counted during the stipulated cycle. Whether or not the counted value is present within a predetermined set value range is discriminated by the microprocessor 21 and the processing speed is monitored. Also, a program is divided into the respective processing units of a desired operating order, one processing start flag is provided, the processing start flag is set at the head part at the time of executing the program for the respective processing units and the processing order is monitored depending on whether or not the processing start flag is set at the end part.</p> |
