6.3
The following shows the registers of the bus controller.
• Bus width control register (ABWCR)
• Access state control register (ASTCR)
• Wait control register H (WCRH)
• Wait control register L (WCRL)
• Bus control register H (BCRH)
• Bus control register L (BCRL )
• Pin function control register (PFCR)
6.3.1
ABWCR 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 except for the on-chip USB and RTC is fixed regardless of the
settings in ABWCR.
Notes: 1. In modes 5 to 7, initial value of each bit is 1. In mode 4, initial value of each bit is 0.

Description
Area 7 to 0 Bus Width Control:
These bits select whether the corresponding area is to
be designated for 8-bit access or 16-bit access.
0: Area n is designated for 16-bit access
1: Area n is designated for 8-bit access
Legend: n = 7 to 0
