CPU CORE
1. Memory Space
The microcontrollers of the MB89680 series offer 64 Kbytes of memory 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 of I/O area, 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 MB89680 series is structured as illustrated below.
