7.3.3
The chip's memory interfaces comprise a basic bus interface that allows direct connection or
ROM, SRAM, and so on, and a burst ROM interface that allows direct connection of burst ROM.
The memory interface can be selected independently for each area.
An area for which the basic bus interface is designated functions as normal space, and an area for
which the burst ROM interface is designated functions as burst ROM space.
