8-Bit Access Areas: Figure 6.5 illustrates data alignment control for 8-bit access space. With 8-bit
access space, the upper data bus (D
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.
16-Bit Access Areas: Figure 6.6 illustrates data alignment control for 16-bit access areas. With
16-bit access areas, the upper data bus (D
accesses. The amount of data that can be accessed at one time is one byte or one word, and a
longword access is executed as two word accesses.
In byte access, whether the upper or lower data bus is used is determined by whether the address is
even or odd. The upper data bus is used for an even address, and the lower data bus for an odd
address.
