<p>PURPOSE:To reduce the frequency of memory accesses at the time of analyzing an instruction code part capable of judging for generating the interruption of a prescribed instruction in the case of processing the prescribed instruction by interruption. CONSTITUTION:This single chip microcomputer 100 is provided with an SP register 114 for holding addresses for storing information with byte length corresponding to length from a prescribed instruction code or an instruction code part capable of recognizing the generation of a trap of the instruction code up to the 1st byte of the succeeding instruction and a control part 120 for controlling interruption processing. When the prescribed instruction code is inputted to the control part 120, the information of the instruction code or byte length is stored in an address determined by the value of the register 114.</p> |
