Section 7 Data Transfer Controller
7.3.4
Figure 7.5 shows how the register information should be located in the address space.
Locate the MRA, SAR, MRB, DAR, CRA, and CRB registers, in that order, from the start address
of the register information (contents of the vector address). In the case of chain transfer, register
information should be located in consecutive areas.
Locate the register information in the on-chip RAM (addresses: H'FFF800 to H'FFFBFF).
