Description
Receive buffer unavailable
This bit indicates that the Next Descriptor in the Receive List is owned by the host and
cannot be acquired by the DMA. Receive Process is suspended. To resume
processing Receive descriptors, the host should change the ownership of the
descriptor and issue a Receive Poll Demand command. If no Receive Poll Demand is
issued, Receive Process resumes when the next recognized incoming frame is
received. This bit is set only when the previous Receive Descriptor was owned by the
DMA.
Received process stopped
This bit is asserted when the Receive Process enters the Stopped state.
Receive watchdog timeout
This bit is asserted when a frame with a length greater than 2,048 bytes is received
(10,240 when Jumbo Frame mode is enabled).
Early transmit interrupt
This bit indicates that the frame to be transmitted was fully transferred to the MTL
Transmit FIFO.
Reserved
Fatal bus error interrupt
This bit indicates that a bus error occurred, as detailed in bits [25:23]. When this bit is
set, the corresponding DMA engine disables all its bus accesses.
Early receive interrupt
This bit indicates that the DMA had filled the first data buffer of the packet. Receive
Interrupt bit 6 in this register automatically clears this bit.
