12.5.3
By specifying bit SM1 in MRA and bit DM1 in MRB to the fixed address mode, a part of transfer
information will not be written back. This function is performed regardless of short or full address
mode. Table 12.5 shows the transfer information writeback skip condition and writeback skipped
registers. Note that the CRA and CRB are always written back regardless of the short or full
address mode. In addition in full address mode, the writeback of the MRA and MRB are always
skipped.
Table 12.5 Transfer Information Writeback Skip Condition and Writeback Skipped
12.5.4
In normal transfer mode, one operation transfers one byte, one word, or one longword of data.
From 1 to 65,536 transfers can be specified. The transfer source and destination addresses can be
specified as incremented, decremented, or fixed. When the specified number of transfers ends, an
interrupt can be requested to the CPU.
Table 12.6 lists the register function in normal transfer mode. Figure 12.7 shows the memory map
in normal transfer mode.
