7.4.2
The external address space bus specifications consist of three elements: bus width, number of
access states, and number of program wait states.
The bus width and number of access states for on-chip memory and internal I/O registers are
fixed, and are not affected by the bus controller.
Bus width: A bus width of 8 or 16 bits can be selected with ABWCR. An area for which an 8-bit
bus is selected functions as an 8-bit access space, and an area for which a 16-bit bus is selected
functions as a 16-bit access space.
