6. Bus Controller
6.5.3
When DRAM space is accessed, the row address and column address are multiplexed. The address
multiplexing method is selected with bits MXC1 and MXC0 in DRCRB according to the number
of bits in the DRAM column address. Table 6.6 shows the correspondence between the settings of
MXC1 and MXC0 and the address multiplexing method.

Note:
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 organization 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: see section 6.4.2, Data
Size and Data Alignment.
