Section 7 Bus State Controller (BSC)
7.3.4
The memory bus width in this LSI can be set for each area. In area 0, the bus width is selected
from 8 bits and 16 bits at a power-on reset by the external pin setting. The bus width of other areas
is set by the register. The correspondence between the memory type, external pin (MD3), and bus
width is listed in table 7.4.
Table 7.4
7.3.5
This LSI supports the big endian and little endian methods of data alignment. The data alignment
is specified using the external pin (MD5) at a power-on reset as shown in table 7.5.
