Multiprocessor-type one-chip microcomputer with dual-mode functional terminals

摘要: A multiprocessor-type one-chip microcomputer, of the type having a plurality processors, each separate address space, programmable ROMs, for storing program data processor, and set functional terminals, with microcomputer including common writing bus control means coupling either or lines to terminals based on setting mode signal. During normal operations are coupled ROM is accessed by processor using addresses in space processor. When new instruction be written ROMs space.
