Section 7 Bus Controller
16-Bit 3-State Access Space: Figures 7.21 to 7.23 show bus timings for a 16-bit 3-state access
space. When a 16-bit access space is accessed, the upper half (D15 to D8) of the data bus is used
for an even address, and the lower half (D7 to D0) for an odd address.
Wait states can be inserted.
