BITS
31:0
Receive Poll Demand (RPD)
When written with any value, the DMAC will check for receive descriptors.
If no descriptors are available, the receive process returns to the suspended
state and bit 7 of the DMAC_STATUS register (receive buffer unavailable -
RU) is not set. A write to this register is only effective if the receive process
is in the suspended state. A Read of this register will timeout and invalid
data will be returned.
Receive Poll Demand Register (RX_POLL_DEMAND)
This register enables the RX DMAC to check for new descriptors.
