PROBLEM TO BE SOLVED: To provide a microprocessor for executing a monitor program by external interruption in an external interruption disabled status without using any hardware exclusive for debug such as an ICE, and for debugging the section of a user program to be executed in the external interruption disabled status. SOLUTION: This microprocessor is provided with an interruption conversion circuit 25, and the output of an external interruption control circuit 22 is invalidated, and the output of an interruption conversion circuit 25 is validated in an external interruption disabled status. When an external interrupting signal INT<SB>k</SB>is applied in this status, an input circuit 26<SB>k</SB>does not input an external interruption signal INT<SB>k</SB>when the storage value of a register 27<SB>k</SB>is 0, and inputs the external interruption signal INT<SB>k</SB>when the storage of the register 27<SB>k</SB>s 1, and transmits this to an interruption signal input terminal 15 exclusive for debug of a processor core 10 as an interruption signal exclusive for debug.
