Hello ,

Hope you are doing well.

I recommend to check section 5.4.2 for details on DMA sources. 

Performing DMA transfers to/from GPIO—Moving data from/to one or more GPIO pins, either unthrottled (that is, as fast as possible), or periodically (using the DMA triggering capability).

Performing DMA transfers from memory to the external bus, or vice-versa—Similar to memory to memory transfers, this is typically done as quickly as possible.

Please let me know if you have further questions.

Best Regards,

Sabina
