MB89870 Series
I
CPU CORE
1. Memory Space
The microcontrollers of the MB89870 series offer a memory space of 64 Kbytes for storing all of I/O, data, and
program areas. The I/O area is located at the lowest address. The data area is provided 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 located at exactly the opposite end, that is, near the highest address. Provide the tables of
interrupt reset vectors and vector call instructions toward the highest address within the program area. The
memory space of the MB89870 series is structured as illustrated below.
