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 cycle 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
(n = 7 to 0)
Reserved
These are read-only bits and cannot be modified.
Wait cycle insertion in area n access is disabled
Wait cycle insertion in area n access is enabled
