8-Bit, 3-State Access Space: Figure 6.12 shows the bus timing for an 8-bit, 3-state access space.
When an 8-bit access space is accessed, the upper half (D15 to D8) of the data bus is used.
When all areas are designated as 8-bit space, the LWR pin can be used as the I/O port. However,
when all areas are designated as 16-bit space, the LWR pin is always fixed high. Wait states can
be inserted.
