Question:
Is it possible to switch between little Endian and big Endian?
Answer:
Yes, it is possible to switch between little endian and big endian by designating an MD5 pin.
At the time of a power-on reset, big endian is engaged when MD5 is low; little endian is engaged when MD5 is high.
This designation is effective for the whole address space, however, endians can not be set for every CS space. Besides, please note that you can not switch endians during CPU operation. For details to set endians,see "Endian/Access Size and Data Alignment" in the section of "Bus State Controller" of Hardware Manual.
