6.4.1
The basic bus interface enables direct connection of ROM, SRAM, and so on.
The bus specifications can be selected with ABWCR, ASTCR, WCRH, and WCRL (see table 6-3).
6.4.2
Data sizes for the CPU and other internal bus masters are byte, word, and longword. The bus controller has a data
alignment function, and when accessing external space, controls whether the upper data bus (D
