Section 11 Direct Memory Access Controller (DMAC)
11.3.5
DMRDADR is a register used to set an address for reloading to the DMA current destination
address register (DMCDADRn).
To enable reloading, set the DMA destination address reload function enable bit (DRLOD) in
DMA control register A (DMCNTAn) to 1. In this case, set both the DMA current destination
address register (DMCDADRn) and DMA reload destination address register (DMRDADRn).
Note: Set this register so that DMA transfer is performed within the correctly aligned address
