ASTCR designates each area as either a 2-state access space or a 3-state access space.
ASTCR sets the number of access states for the external memory space. The number of access
states for on-chip memory and internal I/O registers except for the on-chip USB is fixed regardless
of the settings in ASTCR.
Note: * The on-chip USB and on-chip RTC are allocated to area 6 and area 7, respectively.

Description
Area 7 to 0 Access State Control:
These bits select whether the corresponding area is to
be designated as a 2-state access space or a 3-state
access space. Wait state insertion is enabled or disabled
at the same time.
0: Area n is designated for 2-state access
1: Area n is designated for 3-state access
Legend: n = 7 to 0
Wait state insertion in area n external space is
disabled
Wait state insertion in area n external space is
enabled
