DESCRIPTION
DEFAULT
VALUE(BIN)
Bit 4 = RxON, Receiver Turn On. Writing a “1” to the
0
bit field turns on the Receiver and a “0” turn off the
Receiver.
Bit 0 = TxON, Transmitter Turn On. Writing a “1” to the
0
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-
0
rupt and triggers an interrupt when the transmitter
driver fails. Writing a “0” disables the interrupt.
D1
RLOSIE Writing a “1” to this bit field enables the RLOS inter-
0
rupt and triggers an interrupt when the RLOS condi-
tion occurs. Writing a “0” disables the interrupt.
D2
RLOLIE Writing a “1” to this bit field enables the RLOL inter-
0
rupt and triggers an interrupt when RLOL condition
occurs. Writing a “0” disables the interrupt.
D3
FLIE
Writing a “1” to this bit field enables the FL interrupt
0
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.
D4
PRBSIE Writing a “1” to this bit enables the PRBS bit error
0
interrupt.
D5
CNT_SATIE Writing a “1” to this bit enables the PRBS error-
0
counter saturation interrupt. When the PRBS error
counter reaches 0xFFFF, an interrupt will be gener-
ated.
