When TAOS = 1, all ones are transmitted at the TCLK frequency
Local Loopback
When LLOOP = 1, data input at TPOS, TNEG (TDATA) is internally looped back and output on
RPOS, RNEG (RDATA). TCLK is routed to RCLK, through the jitter attenuator, if activated.
Remote Loopback
When RLOOP = 1, clock and data recovered by the receiver are sent back through the transmit
path and retransmitted. The clock and data are routed through the jitter attenuator, if activated.

Zero Substitution (valid only when TNEG (UBS) is tied high, invoking coder mode).
Setting CODER to “1” enables B8ZS encoding and decoding.
When not in coder mode (TPOS/TNEG are data inputs) setting TAZ to “1” causes all zeros to
be transmitted.
Network Loopback
NLOOP = 1 when a network loopback code has been detected on the received signal.
An interrupt will occur when NLOOP changes state unless a “1” is written to NLOOP disabling
the interrupt.
Loss Of Signal
LOS = 1 when the loss of signal criteria have been met (175 zeros).
LOS = 0 when a valid signal is being received.
An interrupt will occur when LOS changes state unless a “1” is written to LOS disabling the in-
terrupt.
