Selects reference clock for transmitting internal pattern
= 0: uses TCLKn as the reference clock
= 1: uses MCLK as the reference clock
Inverts PRBS
= 0: PRBS data is not inverted
= 1: PRBS data is inverted before transmission and detection
The LOS/AIS criterion is selected as below:
= 0: G.775 (E1) / T1.231 (T1/J1)
= 1: ETSI 300233 & I.431 (E1) / I.431 (T1/J1)
AIS enable during LOS
= 0: AIS insertion on RDPn/RDNn/RCLKn is disabled during LOS
= 1: AIS insertion on RDPn/RDNn/RCLKn is enabled during LOS
Automatically Transmit All Ones during LOS (enabled only when PATT[1:0] = 00)
= 0: disabled
= 1: Automatically Transmit All Ones pattern at TTIPn/TRINGn during LOS.
Reserved.
Defines the length of the user-programmable transmit Inband Loopback activate/deactivate code contained in
TNLP register. The default selection is 5 bits length.
