DMA from this ring is disabled. To re-start transmission from this TxBD ring, this bit must be cleared by writing
1 to it. This bit is set only on a general error condition (as in IEVENT[TXE]), regardless of TQUEUE[EN3], or
if no ready TxBDs can be fetched. DMACTRL[GTS] being set by the user does not cause this bit to be set.
Software should examine the halted queue's buffer descriptors for repeatable error conditions before taking it
out of the halt state. Failure to do so may cause an effective livelock, in which the error condition recurs and
halts all queues again.
Repeatable error conditions that cause halt include:
Bus error:
TxBD programming errors:
DMA from this ring is disabled. To re-start transmission from this TxBD ring, this bit must be cleared by writing
1 to it. This bit is set only on a general error condition (as in IEVENT[TXE]), regardless of TQUEUE[EN4], or
if no ready TxBDs can be fetched. DMACTRL[GTS] being set by the user does not cause this bit to be set.

DMA from this ring is disabled. To re-start transmission from this TxBD ring, this bit must be cleared by writing
1 to it. This bit is set only on a general error condition (as in IEVENT[TXE]), regardless of TQUEUE[EN5], or
if no ready TxBDs can be fetched. DMACTRL[GTS] being set by the user does not cause this bit to be set.
Software should examine the halted queue's buffer descriptors for repeatable error conditions before taking it
out of the halt state. Failure to do so may cause an effective livelock, in which the error condition recurs and
halts all queues again.
Repeatable error conditions that cause halt include:
Bus error:
TxBD programming errors:
• Invalid BD or data address
• Uncorrectable error on BD or data read
• Ready=1 and length=0
• Invalid BD or data address
• Uncorrectable error on BD or data read
• Ready=1 and length=0
• Invalid BD or data address
• Uncorrectable error on BD or data read
• Ready=1 and length=0
