Memory Space
The MB89580B/BW microcontrollers offer a memory space of 64 Kbytes consisting of the I/O, RAM and ROM
areas. The memory space contains areas that are used for specific purposes, such as a general-purpose register
and a vector table.
I/O area (addresses : 0000
H
through 007F
H
)
This area is assigned with the control and data registers, for example, of peripheral functions to be built in.
The I/O area is as accessible as the memory since the area is assigned to a part of the memory space. Direct
addressing also allows the area to be accessed faster.
RAM area
As an internal data area, a static RAM is built in.
The internal RAM capacity varies with the product type.
The area 80
H
to FF
H
can be accessed at high speed with direct addressing.
The area 100
H
to 1FF
H
can be used a general-purpose register area. (The usable area is limited depending
on the product.)
When reset, RAM data becomes undefined.
ROM area
As an internal program area, a ROM is built in.
The internal ROM capacity varies with the product type.
The area FFCO
H
to FFFF
H
should be used for a vector table, for example.
