External bus interface

When the bus width of the area set up as little endian is 32-bit, confine to word (32-bit) access when accessing the relevant area.

When enabling prefetch to the area set to the Little endian, give the access to the corresponding area as word (32 bits) access limitation. In the byte and the half word access, it is not possible to access it correctly.

DMA

Do not transfer DMA to instruction RAM.

Bit Search Module

BSD0, BSD1, and the BDSC register are only the word accesses.
