R/W
D0
RxON
Bit 4 = RxON, Receiver Turn On. Writing a “1” to the
bit field turns on the Receiver and a “0” turn off the
Receiver.
0
D4
TxON
Bit 0 = TxON, Transmitter Turn On. Writing a “1” to the
bit field turn on the Transmitter. Writing a “0” turns off
the transmitter and tri-state the transmitter output
(TTIP/TRing).

0x01
R/W
D0
DMOIE
Writing a “1” to this bit field enables the DMO inter-
rupt and triggers an interrupt when the transmitter
driver fails. Writing a “0” disables the interrupt.
0
D1
RLOSIE
Writing a “1” to this bit field enables the RLOS inter-
rupt and triggers an interrupt when the RLOS condi-
tion occurs. Writing a “0” disables the interrupt.
0
D2
RLOLIE
Writing a “1” to this bit field enables the RLOL inter-
rupt and triggers an interrupt when RLOL condition
occurs. Writing a “0” disables the interrupt.
0
D3
FLIE
Writing a “1” to this bit field enables the FL interrupt
and triggers an interrupt when the FIFO Limit of the
Jitter Attenuator is within 2 bits of overflow/underflow
condition. Writing a “0” disables the interrupt.
NOTE:
This bit field is ignored when the Jitter
Attenuator is disabled.
0
D4
PRBSIE
Writing a “1” to this bit enables the PRBS bit error
interrupt.
0
D5
CNT_SATIE
Writing a “1” to this bit enables the PRBS error-
counter saturation interrupt. When the PRBS error
counter reaches 0xFFFF, an interrupt will be gener-
ated.
