(a) When the data bus width is 16 bits (1/2)
32-bit data is transmitted/received via a 16-bit bus. Therefore, if an even address is specified, the data is
transmitted/received in two accesses in 16-bit units. If an odd address is specified, the lower quarter-
word data is transmitted/received to/from the higher byte (first access), the middle halfword data is
transmitted/received to/from the middle bytes (second access), and the upper quarter-word data is
transmitted/received to/from the lower byte (third access), of the external data bus address.
