1. Memory Space

The MB89530H series has 64 KB of memory space, containing all I/O, data areas, and program areas. The I/

O area is located at the lowest addresses, with the data area placed immediately above. The data area can be

partitioned into register areas, stack areas, or direct access areas depending on the application. The program

area is located at the opposite end of memory, closest to the highest addresses, and the highest part of this

area is assigned to the tables of interrupt and reset vectors and vector call instructions. The following diagram

shows the structure of memory space in the MB89530H series.
