Figures 7.23 to 7.25 show bus timings for a 16-bit, 2-state data access space. When a 16-bit access
space is accessed, the entire address bus (AD15 to AD0) is used for all addresses, and the upper
half (AD15 to AD8) of the data bus is used for even addresses and the lower half (AD7 to AD0) of
the data bus is used for odd addresses. Wait states cannot be inserted in the data cycle.
