Microprocessor with a stop function of the event counter. |
摘要 |
<p>1. A microprocessor comprising a built-in event counter (16) and having a mode selection terminal (MDS) indicating, when it is activated, that the microprocessor should be put in one mode selected from several, and a register of the selected mode (14) retaining in its memory information about the mode which was selected during activation of the mode selection terminal, one of the possible modes being a non-user mode which is employed during the checking of application programs of the microprocessor, characterized in that it comprises a logic circuit (18) which establishes a command for stopping the event counter when the following combination of states exists : - the microprocessor is not in the reinitialization phase, - the mode selection terminal is activated, - the mode selection register indicates that a mode or a group of modes, including a non-user mode, has been selected.</p> |
