Abstract

PURPOSE:To debug a program easily by knowing display by a non-passage detecting circuit when an address which is not entered in a passage-path flag is addressed. CONSTITUTION:An address path storage part 103 sets passage-path flag ''1'' to an address expected to passed through, e.g., AAA, BBB, YYY, and ZZZ from an external writing device 301 under the control of a write control circuit 101. During the execution of a test program, when a program to be tested, after passing through addresses AAA and BBB, passes an address CCC, having a flag ''0'', which is not to be passed through, a non-passage detecting circuit 104 detects and displays that on an external non-passage display device 302. Consequently, the unexpected access of the program to be tested is detected and the contents of the internal register of a stored-program controller 201 are read to know its caused easily.
