The address is calculated by the offset set in DOFR and the contents of DSAR and DDAR.
Although the DMAC calculates only addition, an offset subtraction can be realized by setting the
negative value in DOFR. In this case, the negative value must be 2's complement.
(1)
Figure 10.18 shows a basic operation of a transfer using the offset addition.
In figure 10.18, the offset addition is selected as the transfer source address update and increment
or decrement by 1, 2, or 4 is selected as the transfer destination address. The address update means
that data at the address which is away from the previous transfer source address by the offset is
read from. The data read from the address away from the previous address is written to the
consecutive area in the destination side.
