A microcomputer and an interrupt control method. The microcomputer includes: a plurality of register lists having a plurality of register patterns, respectively, wherein each of plurality of register patterns designates registers, data of which are to be saved in a data memory; an instruction fetch control circuit configured to fetch instruction code from an instruction memory in response to an interrupt request issued based on occurrence of an interrupt factor; and a register data saving control circuit configured to acquire one register pattern from one of the plurality of register lists in response to the interrupt request, and issue a microinstruction based on the acquired register pattern in response to the interrupt request. An instruction executing section is configured to execute the microinstruction prior to the fetched instruction code, to save the data of registers designated based on the acquired register pattern in the data memory.
