DMA channel chaining and request lines

Westin Sykes

When chaining DMA channels, do I need to set up a request line for the secondary DMA request? It seems like I don't, but I'm not sure.

When chaining the DMA channels, the next channel is triggered by the current channel. You do not need to set up a trigger for the next channel.

Thanks and regards,
