8.3.4
Figure 8-5 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).
