Zusammenfassung:PROBLEM TO BE SOLVED: To provide a micro-controller in which respective CPUs execute different applications, so improve processing performance, and the respective CPUs execute an application that requires safety and mutually compare the results thereof to enhance the reliability of write data. SOLUTION: A micro-controller includes a plurality of processing systems made up of a CPU A1, a CPU B5, a memory A2, and a memory B6, and for the instruction processing about specific processing set in advance, the write to peripheral modules A14 to Z16 which are not multiplexed is executed twice, and the write data of the first time and the second time are mutually collated.
