专利汇可以提供Detector of trouble of microprocessor专利检索,专利查询,专利分析的服务。并且PURPOSE:To detect trouble for clock oscillation stop as well as runaway by providing a watchdog timer (monitor timer) function, a triggerrable monostable multivibrator, etc. CONSTITUTION:A microprocessor part 1 incorporates the watchdog timer function, and a clear signal (b) is not outputted in case of runaway. In this case, when the first counter 4 does not receive the signal (b) even when, for example, 13 seconds is over, its output terminal Q is changed from the low level to the high level. This output is inputted as a trigger signal of the second FF8 to generate a reset signal (d) and starts an alarm device to inform the occurrence of trouble. An output QA of the second counter 5 is inputted to the trigger terminal of a retriggerrable monostable multivibrator 7, and a quartz oscillating part 9 is stopped, and the FF8 is set. Thus, the monitor timer function and etc. are provided to detect automatically the trouble of runaway or the like.,下面是Detector of trouble of microprocessor专利的具体信息内容。
