16-Bit 2-State Access Space: Figures 6.13 to 6.15 show bus timings for a 16-bit 2-state access
space in the H8S/2218 Group. When a 16-bit access space is accessed, the upper half (D15 to D8)
of the data bus is used for the even address, and the lower half (D7 to D0) for the odd address.
Wait states cannot be inserted.
