The 8-byte control type uses 4-byte address, 1-byte control, and 3-byte length. The 4-byte address
displays the address of registers subject to internal access. The 1-byte control is for communication
control and 3-byte length shows the length of data subject to continuous access in bytes. Hence,
when the 8-byte control type is applied, the maximal length of data subject to continuous access is
16 MB.
The 4-byte control type uses 2-byte address, 1-byte control, and 1-byte length. The 2-byte address
displays the address of registers subject to internal access. The 1-byte control is for communication
control and 1-byte length shows the length of data subject to continuous access in bytes. Since the
32-bit address map is used internally, the 2-byte address is not enough to express everything. Thus,
the upper 2-byte base address is designated, and then the lower 2-byte address is used.
Table 23 and Table 24 shows the meaning of each bit in the 1-byte control in the 8-byte control type
and the 4-byte control type, respectively.
