MB91302A has non-ROM model, the optimal real time OS internal model, and the IPL (Internal program Loader)
internal model by adding the user ROM model.
*1 : On specific area between 10000H and 2000H, 4 Kbytes RAM can be used.
Refer to “
■INSTRUCTION CACHE”.
*2 : The real time OS internal model stores the real time OS kernel. The program loader internal model stores
the program loader.
Note : Internal ROM emulation : only MB91V301A
