24.2.2 DMA Handshake Control

The DMA handshake interface module is responsible for the assertion and deassertion of the DMA handshake interface, based on the occupancy levels of Tx FIFO and Rx FIFOs.

This interface is provided only for Tx and Rx FIFOs. DMA acts as the flow controller for both the TX and RX channels, meaning it controls the block size.
