(DMA0 not used)
Cautions 1. Setting the same DMA transfer target to multiple DMA channels, and setting multiple DMA
transfer targets to the same DMA channel are prohibited.
2. If using the function of this register, set the DMA trigger factor register (DTFRn (n = 0 to 3)) to
disable DMA requests by interrupt (00H).
