That depends on the handshaking configuration.

I do not really understand your answer. Do you mean hardware or software handshake? Could you please give me an example?

Yes, the two DMA modules are able to transfer data concurrently. The XMC4000 provides multi-layer bus matrix to support this use case.
It depends on source and destination. For example you could do concurrently a transfer from RAM to DAC and a transfer from ADC to USIC.
Furthermore if you use hardware handshaking, it might be that the service request of the peripheral is not connected to both DMA modules.

Please refer to the reference manual for further details.
