Section 6 Bus Controller (BSC)
(2)
Figures 6.17 to 6.19 show the bus timing of 16-bit 3-state access space.
When accessing 16-bit access space, the upper byte data bus (D15 to D8) is used for even
addresses, and the lower byte data bus (D7 to D0) is used for odd addresses. Wait cycles can be
inserted.
