1. Memory Space
The microcontrollers of the MB89130/130A series offer a memory space of 64 Kbytes for storing all of I/O, data,
and program areas. The I/O area is allocated from the lowest address. The data area is allocated immediately
above the I/O area. The data area can be divided into register, stack, and direct areas according to the application.
The program area is allocated from exactly the opposite end, that is, near the highest address. The tables of
interrupt reset vectors and vector call instructions are allocated from the highest address within the program
area. The memory space of the MB89130/130A series is structured as illustrated below.
