Section 11 Direct Memory Access Controller (DMAC)
Table 11.3 shows the DMA source/destination address registers. For details on the rotation address
"indexing" mode, see section 11.11, Rotate Function. Note that when performing pipelined
transfer to or from external devices and modules that support burst access, make sure to set the
direction bits to select address incrementation ("001") or rotation ("011").
Table 11.3 Increment/Decrement for DMA Source/Destination Address Registers
11.3.8
DMCNTA handles the selections of the transfer mode and the condition of transfer, control of
reload functions, and selection of DMA sources.
