Datasheet section 8.2.8 (page 545) states: "When using μDMA to transfer data to and from a peripheral, the peripheral must disable all interrupts to the NVIC."
1) Does that happen automatically or is this something that software must tell the peripheral to do?
2) If an interrupt would occur during the DMA transfer, what happens to it? Is it lost? Is it delayed until completion of the DMA transfer?
