TX/RX Controller TX FIFO Full Status.

0x0 = The TX/RX Controller TX FIFO is not full.

0x1 = The TX/RX Controller TX FIFO is full. Therefore, the TX/RX Controller cannot accept any more frames for transmission.

TX/RX Controller TX FIFO Not Empty Status.

0x0 = TX/RX Controller TX FIFO is empty.

0x1 = TX/RX Controller TX FIFO is not empty and some data is left for transmission.

TX/RX Controller TX FIFO Write Controller Active Status.

0x0 = TX/RX Controller's TX FIFO write controller is inactive.

0x1 = TX/RX Controller's TX FIFO write controller is active and transferring data to the TX FIFO.

TX/RX Controller's TX FIFO Read Controller Status. This field indicates the state of the TX FIFO read controller:

0x0 = IDLE state

0x1 = READ state (transferring data to MAC transmitter)

0x2 = Waiting for TX Status from MAC transmitter

0x3 = Writing the received TX Status or flushing the TX FIFO

MAC Transmitter PAUSE.

0x0 = MAC transmitter is not in PAUSE mode.

0x1 = Indicates that the MAC transmitter is in the PAUSE condition (in the full-duplex only mode) and hence does not schedule any frame for transmission.

MAC Transmit Frame Controller Status. This field indicates the state of the MAC Transmit Frame Controller module:

0x0 = IDLE state

0x1 = Waiting for status of previous frame or IFG or backoff period to be over

0x2 = Generating and transmitting a PAUSE control frame (in the full-duplex mode)

0x3 = Transferring input frame for transmission

MAC MII Transmit Protocol Engine Status.

0x0 = MAC MII transmit protocol engine is not actively transmitting data.

0x1 = MAC MII transmit protocol engine is actively transmitting data and is not in the IDLE state.

TX/RX Controller RX FIFO Fill-level Status. This field gives the status of the fill-level of the RX FIFO. The FIFO threshold is programmed by the TCC field in the Ethernet MAC DMA Operation Mode (EMACDMAOPMODE) register.

0x0 = RX FIFO Empty

0x1 = RX FIFO fill level is below the flow-control deactivate threshold

0x2 = RX FIFO fill level is above the flow-control activate threshold

0x3 = RX FIFO Full

TX/RX Controller Read Controller State. This field gives the state of the RX FIFO read Controller.

0x0 = IDLE state

0x1 = Reading frame data

0x2 = Reading frame status (or timestamp)

0x3 = Flushing the frame data and status

TX/RX Controller RX FIFO Write Controller Active Status.

0x0 = The MTL RX FIFO Write Controller is inactive.

0x1 = MTL RX FIFO Write Controller is active and is transferring a received frame to the FIFO.

MAC Receive Frame Controller FIFO Status. When high, this field indicates the active state of the small FIFO Read and Write controllers of the MAC Receive Frame Controller Module.

MAC MII Receive Protocol Engine Status.

0x0 = MAC MII receive protocol engine is not actively receiving data.

0x1 = Indicates that the MAC MII receive protocol engine is actively receiving data and not in IDLE state.
