A microprocessor comprises a built-in event counter having a mode selection terminal indicating when it is activated. The microprocessor should be put in one mode selected from several, and a register of the selected mode retaining in its memory information about the mode which was selected during activation of the mode selection terminal. One of the possible modes is a non-user mode which is employed during the checking of application programs of the microprocessor. It comprises a logic circuit which establishes a command for stopping the event counter when the following combination of states exists. |
