PURPOSE:To prevent event detection and real time trace from being performed during real time OS program execution. CONSTITUTION:The chip select of an event detector 5 and a real time tracer 6 is enabled by using an event trace enable signal SIT which is the logical product of a real time OS operation signal SOO, which is made active by writing '1' in a real time OS operation flag 2 and made inactive by writing '0', and a supervisor mode signal SSM. |
