7.5.3
As with the basic bus interface, program waits can be inserted in the burst ROM interface initial
cycle (full access). See section 7.4.5, Wait Control.
Wait states cannot be inserted in the burst cycle.

7.6.1
When the chip accesses external space, it can insert a 1-state idle cycle (T
the following two cases: (1) when read accesses between different areas occur consecutively, and
(2) when a write cycle occurs immediately after a read cycle. By inserting an idle cycle it is
possible, for example, to avoid data collisions between ROM, with a long output floating time, and
high-speed memory, I/O interfaces, and so on.
