摘要： An information processing system which makes it possible to protect information stored in the ROM of the system from unauthorized access by means of a debug tool. The information processing system includes a ROM for storing an unlocking program and a user program; a CPU for executing said unlocking program and said user program stored in said ROM; an on-chip debug circuit serving to output debug information of said user program as executed by said information processing system; and a debug function disabling circuit serving to disable debug functions of said on-chip debug circuit at power up and to enable the debug functions of said on-chip debug circuit when said unlocking program has been executed.
