EnTxBErr [24]: Enable Transmit Bus ERROR interrupt
Default value: 0
Set this bit to enable the interrupt, which is generated if system bus access error from Tx to system
memory occurred. If the interrupt is triggered, the Tx state machine will stay at Halt state. The software
reset is recommended while this interrupt occurred.
EnTDU [23]: Enable Transmit Descriptor Unavailable interrupt
Default value: 0
Set this bit to enable the interrupt, which is generated if transmit descriptors owned to the TxDMA is
unavailable. That means, if the TxDMA finds the ownership of descriptors is not belonged to TxDMA, it
will generate an interrupt and Tx operation will be ceased till the user issues a write command to
Transmit Start Demand register to restart Tx operation.
EnLC [22]: Enable Late Collision interrupt
Default value: 0
Set this bit to enable the interrupt, which is generated if a collision occurs after 512 bit times.
EnTXABT [21]: Enable Transmit Abort interrupt
Default value: 0
