Reset Value:
This register, when read, returns details of the status of a transmit. Once read, individual bits may be cleared by writing a
one to them. It is not possible to write a bit to one by writing to the register.
• UND: Transmit Underrun
• COMP: Transmit Complete
• BEX:
• TGO: Transmit Go
• RLE: Retry Limit Exceeded

Buffers Exhausted Mid Frame
This bit is set when transmit DMA was not able to read data from memory, either because the bus was not granted in time or
because a used bit was read midway through frame transmission. If this occurs, the transmitter forces bad CRC.
Write a one to clear this bit.
0: No transmit underrun.
1: Transmit underrun.
This bit is set when a frame has been transmitted.
Write a one to clear this bit.
0: Transmit is not completed.
1: Transmit is completed.
This bit is set if the buffers run out during transmission of a frame. Then transmission stops, FCS shall be bad and TX_ER is
asserted.
Write a one to clear to this bit.
0: Buffer is not exhausted.
1: Buffer is exhausted.
0: Transmit is inactive.
1: Transmit is active.
This bit is set when retry limit has exceeded.
Write a one to clear this bit.
0: Retry limit is not exceeded.
