6.2.1
Modes 5 to 7
Mode 4
ABWCR is an 8-bit readable/writable register that designates each area for either 8-bit access or 16-bit access.
ABWCR sets the data bus width for the external memory space. The bus width for on-chip memory and internal I/O
registers is fixed regardless of the settings in ABWCR.
After a power-on reset and in hardware standby mode, ABWCR is initialized to H'FF in modes 5 to 7,*
mode 4. It is not initialized by a manual reset*
Notes: 1. In ROMless version, modes 6 and 7 are not available.
Bits 7 to 0—Area 7 to 0 Bus Width Control (ABW7 to ABW0): These bits select whether the corresponding area is to
be designated for 8-bit access or 16-bit access.
