Abstract
PURPOSE: To obtain a detector that adapts itself flexibly to system constitution by reading out information from an address package area table by using the address of the time when a microprocessor accesses a memory.
CONSTITUTION: An address packaged area table 10 which stores the signals discriminating the address packaged areas and address non-packaged areas of a memory 2 which a microporcessor 1 uses into said corresponding addresses is provided. The information relating to the address packaged areas of the memory 2 is written into the table 10 by the execution of the initiation program of the microprocessor 1. Further, the information is read out from the table 10 by using the address of the time when the microprocessor 1 accesses the memory 2 and when the information which is the address non-packaged area is obtained, it is recognized that said access is to the incorrect address.
