1. Memory Space

The microcontrollers of the MB89610 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 MB89610 series is structured as illustrated below.
