2.3 Access space
2.3 Access space
Figure 2.3.1 shows the M37702’s access space.
By combination of the program counter (PC), which is 16 bits of structure, and the program bank register
(PG), a 16-Mbyte space from addresses 000000
of an external area, refer to “Chapter 12. CONNECTION WITH EXTERNAL DEVICES.”
The memory and I/O devices are allocated in the same access space. Accordingly, it is possible to perform
transfer and arithmetic operations using the same instructions without discrimination of the memory from
I/O devices.
