LLOOP Pin Enable—Allows the use of the LLOOP hardware pin instead of the LLOOP
register bit to control loopbacks.
RLOOP Pin Enable—Allows the use of the RLOOP hardware pin instead of the RLOOP
register bit to control loopbacks.
0 = Use RLOOP register bit
1 = Use RLOOP pin
Receive Analog Loss of Signal Detect—Indicates receiver analog loss of signal.
Receive Loss of Signal Detect—Indicates receiver loss of signal.
Transmit Loss of Clock Detect—Indicates loss of transmit clock, TCLK.
Transmit Loss of Signal Detect—Indicates a transmitter signal fault detected by the DPM.
Transmit Short Circuit Detect—Indicates transmitter output overload.
Jitter Attenuator Error Detect—Indicates jitter attenuator FIFO overflow or underrun.
Bipolar Violation Detect—Indicates a bipolar violation error. If ZCS encoding/decoding is
enabled, BPV is asserted only for bipolar violations which are not part of the ZCS code.
