2 : A d d r e s s b u s w h e n i n s e p a r a t e b u s m o d e .
In memory expansion mode, select a 8-bit multiplex bus.
The processor operates using the separate bus after reset is revoked, so the entire space multiplexed
bus cannot be chosen in microprocessor mode.
The higher-order address becomes a port if the entire space multiplexed bus is chosen, so only 256
bytes can be used in each chip select.
