PURPOSE:To read out the latest by writing the information of a new interruption processing on a segment area neighboring to the segment area on which the last write is performed, detecting an unwritten segment area neighboring to a written area, and reading out a vector storage area from a position traced back by a prescribed number of bytes from a detected segment area. CONSTITUTION:New interruption information in which interruption information written on the segment area C1 of the vector storage area 3 is corrected is written on the segment area C2, and the information written on the segment area C2 is read out at the time of performing an interruption processing, and a processing according to the information is performed. Thereby, the information of the new interruption processing is written instead of the present information as far as the unwritten segment area exists, and rewritten latest information is read out at the time of performing the interruption processing, and the processing according to the information can be performed. |
