1. Memory Space
The MB89530A 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 MB89530A series.
