Table35-9. FCCE/FCCM Field Descriptions

Bits Name Description
0–7 Reserved, should be cleared.
8 GRA Graceful stop complete. A graceful stop, initiated by the GRACEFUL STOP TRANSMIT command, is
complete. When the command is issued, GRA is set as soon the transmitter finishes sending a
frame in progress. If no frame is in progress, GRA is set immediately.
9 RXC RX control. A control frame has been received (FSMR[FCE] must be set). As soon as the transmitter
finishes sending the current frame, a pause operation is performed.
10 TXC TX control. An out-of-sequence frame was sent.
11 TXE Tx error. An error occurred on the transmitter channel.
12 RXF Rx frame. Set when a complete frame is received on the Ethernet channel.
13 BSY Busy condition. Set when a frame is received and discarded due to a lack of buffers.
14 TXB Tx buffer. Set when a buffer has been sent on the Ethernet channel.
15 RXB Rx buffer. A buffer that was not a complete frame is received on the Ethernet channel.
16–31 Reserved, should be cleared.
