(2) Byte access (8 bits)
(a) 16-bit data bus width
(b) 8-bit data bus width
8-bit data is transmitted/received via a 16-bit bus. Therefore, if an even address is specified, the lower
byte of the external data bus address is accessed. If an odd address is specified, the higher byte of the
external data bus address is accessed.
8-bit data is transmitted/received via an 8-bit bus. Therefore, the specified even/odd address of the
external data bus is accessed.
