Data sizes for the CPU and other internal bus masters are byte, word, and longword. The bus
controller has a data alignment function, and controls whether the upper byte data bus (D15 to D8)
or lower data bus (D7 to D0) is used according to the bus specifications for the area being
accessed (8-bit access space or 16-bit access space), the data size, and endian format when
accessing external address space.
(1)
With the 8-bit access space, the lower byte data bus (D7 to D0) is always used for access. The
amount of data that can be accessed at one time is one byte: a word access is performed as two
byte accesses, and a longword access, as four byte accesses.
Figures 8.10 and 8.11 illustrate data alignment control for the 8-bit access space. Figure 8.10
shows the data alignment when the data endian format is specified as big endian. Figure 8.11
shows the data alignment when the data endian format is specified as little endian.
