Section 7 Bus Controller
16-Bit 2-State Access Space: Figures 7-7 to 7-9 show bus timings for a 16-bit 2-state access
space. 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.
