Section 6 Bus Controller
16-Bit, 3-State Access Space
Figures 6.10 to 6.12 show the bus timing for 16-bit, 3-state access space. When 16-bit access
space is accessed, the upper data bus (D15 to D8) is used for even addresses and the lower data
bus (D7 to D0) for odd addresses.
Wait states can be inserted.
