10.5.2
By setting the SM1 and DM1 bits to the fixed address mode, a part of transfer information will not
be written back (writeback skipped). This function is performed regardless of the short address
mode or full address mode.
Table 10.4 shows the transfer information writeback skip condition and writeback skipped
registers. Note that CRA and CRB are always written back regardless of the short address mode or
full address mode. In addition in full address mode, the writeback of MRA and MRB are always
skipped.
