External Address Space Access Timing
The external address space is accessed with an 8-bit or 16-bit data bus width in a two-state or
three-state bus cycle. Figure 4.5 shows the read timing for two-state and three-state access. Figure
4.6 shows the write timing for two-state and three-state access. In three-state access, wait states
can be inserted. For further details, refer to the relevant microcontroller hardware manual.
