1. Memory Space
The microcontrollers of the MB89890 series offer 64 Kbytes of memory 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 MB89890 series is structured as illustrated below:
