<p>A macroservice engine is provided to exclusively carry out a sequence control in a processing of a macroservice. On the other hand, a command execution unit carries out no macroservice, but generates a bus cycle exciting request for a bus control unit, when an access request signal is generated to access a memory or peripheral registers included in a microcomputer. Thus, a processing of interruption is carried out with high speed, and a burden of a central processing unit is relieved in an interruption process. <IMAGE></p> |
