Symbol
DRCn
(2) DMA operation control register n (DRCn)
DRCn is a register that is used to enable or disable transfer of DMA channel n.
Rewriting bit 7 (DENn) of this register is prohibited during operation (when DSTn = 1).
DRCn can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Caution The DSTn flag is automatically cleared to 0 when a DMA transfer is completed.
Remark
DMAC waits for a DMA trigger when DSTn = 1 after DMA operation is enabled (DENn = 1).
DMAC waits for a DMA trigger when DSTn = 1 after DMA operation is enabled (DENn = 1).
When a software trigger (STGn) or the start source trigger set by IFCn3 to IFCn0 is input, DMA transfer is started.
When DMA transfer is completed after that, this bit is automatically cleared to 0.
Write 0 to this bit to forcibly terminate DMA transfer under execution.

Writing the DENn flag is enabled only when DSTn = 0. When a DMA transfer is terminated
without waiting for generation of the interrupt (INTDMAn) of DMAn, therefore, set DSTn to 0
and then DENn to 0 (for details, refer to 15.5.7 Forcible termination by software).
