DESCRIPTIONS
-
The Transmission Halted high indicates the next normal packet transmission
process will be halted because the bit TXON of MCMDR is disabled be S/W.
1’b0: Next normal packet transmission process will go on.
1’b1: Next normal packet transmission process will be halted.
The Signal Quality Error high indicates the SQE error found at end of packet
transmission on 10Mbps half-duplex mode. The SQE error check will only be
done while both bit EnSQE of MCMDR is enabled and EMC is operating on
10Mbps half-duplex mode.
1’b0: No SQE error found at end of packet transmission.
1’b0: SQE error found at end of packet transmission.
The Transmission Paused high indicates the next normal packet
transmission process will be paused temporally because EMC received a
PAUSE control frame, or S/W set bit SDPZ of MCMDR and make EMC to
transmit a PAUSE control frame out.
1’b0: Next normal packet transmission process will go on.
1’b1: Next normal packet transmission process will be paused.
The Deferred Transmission high indicates the packet transmission has
deferred once. The DEF is only available while EMC is operating on half-
duplex mode.
1’b0: Packet transmission doesn’t defer.
1’b1: Packet transmission has deferred once.
The Collision Count indicates the how many collision occurred consecutively
during a packet transmission. If the packet incurred 16 consecutive collisions
during transmission, the CCNT will be 4’h0 and bit TXABT will be set to 1.
-
The RxFIFO Full indicates the RxFIFO is full due to four 64-byte packets are
kept in RxFIFO and the following incoming packet will be dropped.
1’b0: The RxFIFO is not full.
1’b1: The RxFIFO is full and the following incoming packet will be dropped.
The Receive Halted high indicates the next normal packet reception process
will be halted because the bit RXON of MCMDR is disabled be S/W.
1’b0: Next normal packet reception process will go on.
1’b1: Next normal packet reception process will be halted.
The Control Frame Received high indicates EMC receives a flow control
frame. The CFR only available while EMC is operating on full duplex mode.
1’b0: The EMC doesn’t receive the flow control frame.
1’b1: The EMC receives a flow control frame.
