6.9.2
As with the basic bus interface, either program wait insertion or pin wait insertion using the WAIT
pin can be used in the initial cycle (full access) on the burst ROM interface. See section 6.5.4,
Wait Control. Wait states cannot be inserted in a burst cycle.
6.9.3
When a write access to burst ROM space is executed, burst access is interrupted at that point and
the write access is executed in line with the basic bus interface settings. Write accesses are not
performed in burst mode even though burst ROM space is designated.
