Description
Area 7 to 0 Bus Width Control
These bits select whether the corresponding
area is to be designated as 8-bit access space
or 16-bit access space.
0: Area n is designated as 16-bit access space
1: Area n is designated as 8-bit access space
Description
Area 7 to 0 Access State Control
These bits select whether the corresponding
area is to be designated as 2-state access
space or 3-state access space. Wait state
insertion is enabled or disabled at the same
time.
0: Area n is designated as 2-state access space
1: Area n is designated as 3-state access space
Wait state insertion in area n access is
disabled
Wait state insertion in area n access is
enabled
