7
Tx FIFO Reset
R/W
0
0 to 1 transition resets internal FIFO memory and its read-write pointers.
NOTE: This bit-field is only active if the XRT72L71 is configured to operate
in the “ATM UNI” Mode.
6
Discard Upon PErr
R/W
0
0: “Transmit UTOPIA” Parity errors do not result in cell discard
1: Cells in which a “Transmit UTOPIA” parity error is detected are discarded.
NOTE: This bit-field is only active if the XRT72L71 is configured to operate
in the “ATM UNI” Mode.
5
Tx Parity Error Interrupt
Enable
R/W
0
0: Disables the “Transmit UTOPIA Detection of Parity Error” Interrupt.
1: Enables the “Transmit UTOPIA Detection of Parity Error” Interrupt.
NOTE: This bit-field is only active if the XRT72L71 is configured to operate
in the “ATM UNI” Mode.
4
Tx FIFO Overrun Interrupt
Enable
R/W
0
0: Disables the “TxFIFO Overrun” interrupt.
1: Enables the “TxFIFO Overrun” interrupt.
NOTE: This bit-field is only active if the XRT72L71 is configured to operate
in the “ATM UNI” Mode.
3
