When an address break is set in the data read cycle or data write cycle, the data bus used will
depend on the combination of the byte/word access and address. Table 4.1 shows the access and
data bus used. When an I/O register space with an 8-bit data bus width is accessed in word size, a
byte access is generated twice. For details on data widths of each register, see section 20.1,
Register Addresses (Address Order).
