Example 3) After access the external area, only the address bus changes
In this example, after access to the external area(i), an access to the area
indicated by the same chip select signal(i) will occur in the next cycle. In
this case, the address bus changes between the two cycles, but the chip
select signal does not change.
Example 1) After access the external area, both the address signal and
In this example, after access to the external area(i), an access to the area
indicated by the other chip select signal(j) will occur in the next cycle. In
this case, both the address bus and the chip select signal change between
the two cycles.

In this example, an access to the internal ROM or the internal RAM in the
next cycle will occur, after access to the external area. In this case, the
chip select signal changes between the two cycles, but the address does
not change.
Example 4) After access the external area, either the address signal and
In this example, any access to any area does not occur in the next cycle
(either instruction prefetch does not occur). In this case,either the address
bus and chip select signal do not change between the two cycles.
