DMA0 transfer request
DMA1 transfer request
DMA2 transfer request
<1> DMA0 transfer request
<2> A new DMA0 transfer request is generated during DMA0 transfer.
<3> Requests for DMA0 and DMA1 are generated at the same time.
<4> Requests for DMA0, DMA1, and DMA2 are generated at the same time.
Mode of processing
System clock
DMA transfer
→ A DMA transfer request for the same channel is ignored during DMA transfer.
→ The DMA0 request is ignored (a DMA transfer request for the same channel during transfer is ignored).
→ The DMA1 request is acknowledged.
→ The DMA1 request is ignored (a DMA transfer request for the same channel during transfer is ignored).
→ The DMA0 request is acknowledged according to priority. The DMA2 request is held pending. (The next transfer will occur for DMA2).
