Section 6 Bus Controller (BSC)
(2)
With the 16-bit access space, the upper byte data bus (D15 to D8) and lower byte data bus (D7 to
D0) are used for accesses. The amount of data that can be accessed at one time is one byte or one
word.
Figures 6.12 and 6.13 illustrate data alignment control for the 16-bit access space. Figure 6.12
shows the data alignment when the data endian format is specified as big endian. Figure 6.13
shows the data alignment when the data endian format is specified as little endian.
In big endian, byte access for an even address is performed by using the upper byte data bus and
byte access for an odd address is performed by using the lower byte data bus.
In little endian, byte access for an even address is performed by using the lower byte data bus, and
byte access for an odd address is performed by using the third byte data bus.
