(3) Destination address register
It isn't possible to change until it cancels a transfer mode after setting a transfer mode register. It becomes a transfer
error when rewriting before canceling a transfer mode. The relation of the address of SDRAM and instruction RAM of
internal CPU is as in Figure 3-4 and 3-5. The addressing of SDRAM becomes a 32 address by 4-word unit (128
bytes).
