PURPOSE: To provide a CPU operation abnormality detection system which can shorten the time needed for detection of such abnormality as the runaway of a CPU, etc. CONSTITUTION: The access inhibition information is generated by the execution of an initialization program that is stored in a ROM of a ROM/RAM/input- output control circuit part 20 and then written in a monitoring point memory part 1 by a memory control circuit part 2. Then the part 2 reads the access inhibition information corresponding to an execution address out of the part 1 and inputs the inhibition information to a CPU control circuit part 11 via a synthesization circuit 3. |
