Bits 7 to 0—Areas 7 to 0 Bus Width Control (ABW7 to ABW0): These bits select 8-bit access
or 16-bit access to the corresponding address areas.
ABWCR specifies the bus width of external memory areas. The bus width of on-chip memory and
internal I/O registers is fixed and does not depend on ABWCR settings. These settings are
therefore meaningless in single-chip mode (mode 7).
6.2.2
ASTCR is an 8-bit readable/writable register that selects whether each area is accessed in two
states or three states.
ASTCR is initialized to H'FF by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bits 7 to 0—Areas 7 to 0 Access State Control (AST7 to AST0): These bits select whether the
corresponding area is accessed in two or three states.
ASTCR specifies the number of states in which external areas are accessed. On-chip memory and
internal I/O registers are accessed in a fixed number of states that does not depend on ASTCR
settings. These settings are therefore meaningless in single-chip mode (mode 7).
