专利汇可以提供Runaway stopping device of microprocessor专利检索,专利查询,专利分析的服务。并且PURPOSE:To stop automatically operation of a microprocessor and its peripheral circuit by providing a watchdog timer (monitor timer) function and etc. and detecting runaway to hold them in a reset state. CONSTITUTION:A microprocessor 1 incorporates the watchdog timer function besides a normal function. When the processor 1 runs away, an output (b) is not outputted, and consequently, a counter 4 is not reset; and if this state continued for, for example, 13 seconds, a circuit 4 is changed from a low level to a high level. Then, the input T of the second FF6 is set, and a reset pulse is inputted to the reset terminal (d) of the processor 1 through a gate 8 together with the output of a reset pulse generating circuit 3 to stop the operation automatically. The monitor timer function is provided to detect runaway in this manner, thus stopping the microprocessor or the like automatically.,下面是Runaway stopping device of microprocessor专利的具体信息内容。
