dmagrp_receive_poll_demand

         Register 2 (Receive Poll Demand Register) 

The Receive Poll Demand register enables the receive DMA to check for new descriptors. This command is used to wake up the Rx DMA from the SUSPEND state. The RxDMA can go into the SUSPEND state only because of the unavailability of descriptors it owns. When this register is read, it always returns zero.

Receive Poll Demand

When these bits are written with any value, the DMA reads the current descriptor pointed to by Register 19 (Current Host Receive Descriptor Register). If that descriptor is not available (owned by the Host), the reception returns to the Suspended state and the Bit 7 (RU) of Register 5 (Status Register) is not asserted. If the descriptor is available, the Rx DMA returns to the active state.
