ABWCR specifies the data bus width of external memory areas. The data bus width of on-chip
memory and registers is fixed, and does not depend on ABWCR settings.
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—Area 7 to 0 Access State Control (AST7 to AST0): These bits select whether the
corresponding area is accessed in two or three states.
