Table 6.5
Legend:
Note:
6.6.3
If a 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, D15 to D8, is enabled, while in 16-bit DRAM
space both the upper and lower halves of the data bus, D15 to D0, are enabled.
Access sizes and data alignment are the same as for the basic bus interface: see section 6.5.1, Data
Size and Data Alignment.
