PROBLEM TO BE SOLVED: To achieve a function for restoring a central processing circuit in a processor from an abnormal state to a desired normal state, with a simple circuit configuration. SOLUTION: The central processing circuit (140) includes a register (149) for indicating validity or invalidity of a forced jump in relation to a conditional branch instruction, and determines that the branch condition is satisfied if the register (149) indicates validity when executing the conditional branch instruction. The register (149) transits from an invalid state to a valid state, when a timer circuit (130) issues an interrupt request. A program to be stored in a memory circuit (110) is generated such that the satisfaction of the branch condition of a conditional branch instruction is made the termination condition for loop processing, in relation to loop processing using a conditional branch instruction.
