Pause DMA if the receiver peripheral cannot accept data for a while

I could run the DMA core to read data from the onchip memory and send to one peripheral. Is there a way to pause the DMA core because the peripheral cannot accept new data for a while? Thanks

You try try asserting the waitrequest signal from your peripheral so that it will backpressure the DMA.
