MB89630 SERIES HARDWARE MANUAL
2-4
(1) I/O area
This area is where various resources such as control and data registers are located. The memory map
for the I/O area is given in Appendix 1.
(2) RAM area
This area is where the static RAM is located. Addresses from 0100
H to 01FFH are also used as the
general-purpose register area.
(3) External area
When data is read and written from and to this area with the external-bus function specified, the external
de vice is accessed via ports 0, 1, and 2. Examples of expanding the external memory and peripheral
resources by using the external-bus pins are described in 3.4 Memory Access Modes.
(4) ROM area
This area is where the internal ROM is located. Addresses from FFC0
H to FFFFH are also used for the
tables of interrupt and reset vectors and vector-call instructions. Table 2-1 shows the correspondence
between each interrupt number or reset and the table addresses to be referenced for the MB89630
series of microcon trollers.
