Figure 10.19 shows the XY conversion using the offset addition in repeat transfer mode.
In figure 10.19, the source address side is specified to the repeat area by DACR and the offset
addition is selected. The offset value is set to 4 × data access size (when the data access size is
longword, H'00000010 is set in DOFR, as an example). The repeat size is set to 4 × data access
size (when the data access size is longword, the repeat size is set to 4 × 4 = 16 bytes, as an
example). The increment or decrement by 1, 2, or 4 is specified as the transfer destination address.
A repeat size end interrupt is requested when the RPTIE bit in DACR is set to 1 and the repeat
size of transfers is completed.
