the transmitter is put into a pause state after completion of the frame currently being transmitted.
0 No graceful stop interrupt.
1 Graceful stop requested.
MAC’s maximum frame length register and MACCFG2[Huge Frame] is cleared. Frame truncation occurs
when this condition occurs.
0 Transmitted frame length not exceeding maximum frame length.
1 Transmitted frame length exceeding maximum frame length when MACCFG2[Huge Frame] = 0.
0 Control frame not transmitted.
1 Control frame transmitted.

0 No transmit buffer descriptor updated.
1 Transmit buffer descriptor updated.
transmit buffer descriptor (TxBD) was updated. This only occurs if the I (interrupt) bit in the status word of
the buffer descriptor is set. The specific transmit queue that was updated has its TXF bit set in TSTAT.
0 No frame transmitted/TxBD not updated.
1 Frame transmitted/TxBD updated.

Late collision. This bit indicates that a collision occurred beyond the collision window (slot time) in
half-duplex mode. The frame is truncated with a bad CRC and the remainder of the frame is discarded.
0 No late collision occurred.
1 Late collision occurred.
Busy condition interrupt. Indicates that a frame was received and discarded due to a lack of buffers.
MIB counter overflow. This interrupt is asserted if the count for one of the MIB counters has exceeded the

• A graceful stop, which was initiated by setting DMACTRL[GTS], is now complete.
• A transmission of a flow control PAUSE frame, which was initiated by setting TCTRL[TFC_PAUSE], is
now complete.
