6.3.1
ACSCR designates each area in the external address space as either 8-bit access space or 16-bit
access space. ACSCR designates each area in the external address space as either 2-state access
space or 3-state access space.
ACSCR is initialized to H'FF at a reset or in hardware standby mode but not initialized in software
standby mode.

Description
Area 3 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
Area 3 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
