Section 12 Bus State Controller (BSC)
12.3.4
The memory bus width in this LSI can be set for each area. In area 0, external pins can be used to
select byte (8 bits), word (16 bits), or longword (32 bits) on power-on reset. The memory bus
width of the other area is set by the register. The correspondence between the memory type,
external pins (MD3, MD4), and bus width is listed in the table below.

Note:
12.3.5
This LSI supports the big endian and little endian methods of data alignment. The data alignment
is specified using the external pin (MD5) at power-on reset as shown in table 12.5.
