units.
These 8-bit registers are used to control the DMA transfer start trigger through interrupt requests from on-chip
The interrupt requests set with these registers serve as DMA transfer start factors.
These registers can be read or written in 8-bit or 1-bit units. However, only bit 7 (DFn) can be read/written in 1-bit
Note The DFn bit is a write-only bit. Write 0 to this bit to clear a DMA transfer request if the interrupt that is
Cautions 1. Be sure to stop DMA operation before making changes to DTFRn register settings.
