Abstract
A semiconductor device including a register controller and a processor which includes a register is provided. The register includes a first circuit and a second circuit which includes a plurality of memory portions. The first circuit and the plurality of memory portions can store data by an arithmetic process of the processor. Which of the plurality of memory portions the data is stored in depends on a routine by which the data is processed. The register controller switches the routine in response to an interrupt signal. The register controller can make any one of the plurality of memory portions which corresponds to the routine store the data in the first circuit every time the routine is switched. The register controller can make data stored in any one of the plurality of memory portions which corresponds to the routine be stored in the first circuit every time the routine is switched.
