PURPOSE:To present a function which monitors resources closed in a microcomputer from the external without hindering the microcomputer in its execution. CONSTITUTION:The address of a register incorporated in a microcomputer 100 is preliminarily set from the external, and data on an internal data bus 108 is taken in at the timing of coincidence with the register address outputted onto an internal register address bus 107 and is outputted to the external through a serial interface 300. Since information of the resource closed in the microcomputer is acquired in this manner without temporarily stopping the execution of the microcomputer, a machine as the control object, is free from runaway and trouble. Further, development in real time is performed in the same manner as execution because the execution of the microcomputer is not stopped. |
