<1> When a DMA transfer request is generated, the corresponding DF bit is set (1).
<2> Starting DMA0 transfer clears the DF0 bit (0).
<3> Starting DMA1 transfer clears the DF1 bit (0).
<4> After the DMA transfer on channel 0 is complete, a new DMA transfer is requested for channel 0.
<5> Starting DMA0 transfer clears the DF0 bit (0). Transfer on channel 2 is held pending.
Remarks 1. Transfer in the order of DMA0 → DMA1 → DMA0 (DMA2 is held pending.)
