6.5.4
If the bit in ABWCR corresponding to an area designated as DRAM space is set to 1, that area is
designated as 8-bit DRAM space; if the bit is cleared to 0, the area is designated as 16-bit DRAM
space. In 16-bit DRAM space, ×16-bit configuration DRAM can be connected directly.
In 8-bit DRAM space the upper half of the data bus, D
space both the upper and lower halves of the data bus, D
Access sizes and data alignment are the same as for the basic bus interface. For details, see section
6.4.2, Data Size and Data Alignment.
