专利汇可以提供Interruption controlling circuit专利检索,专利查询,专利分析的服务。并且PURPOSE:To prevent the runaway of a program, by generating a power-on reset signal to return the program to the initial state when a vector address generation start signal is issued or an interruption request disappears erroneously because of a malfunction. CONSTITUTION:When an interruption is caused from a timer, a terminal, or the like, an interruption start signal Pi is outputted from timers 1 and 2 and INTs 1 and 2 to an arithmetic logical unit 3, and saving of contents of registers 4a- 4d to a memory 7 is started after an executing instuction is terminated. If the interruption is started by the malfunction of a timer counter or the like to output a vector address generation start signal Ps or to lose the interruption request, the state of no interruption signal from timers 1 and 2 or INTs 1 and 2 to a vector address generating part 10 is set. Then, a signal from a power-on reset terminal RES is inputted to the generating part 10 through a NOR gate 8 and an OR gate 9, and a specific vector address is generated from the generating part 10 and is loaded to a program counter 4d, and registers 4a-4d are set to the initial state.,下面是Interruption controlling circuit专利的具体信息内容。
