These bits select the internal pattern and insert it into the transmit data stream.
= 00: normal operation (PATT_CLK = 0) / insert all zeros (PATT_CLK = 1)
= 01: insert All Ones
= 10: insert PRBS (E1: 2
= 11: insert programmable Inband Loopback activate or deactivate code
= 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 (enabled only when PATT[1:0] = 01)
= 0: disabled
= 1: Automatically Transmit All Ones pattern at TTIPn/TRINGn during LOS.
Reserved
= 0: disables Automatic Remote Loopback (normal transmit and receive operation)
= 1: enables Automatic Remote Loopback
= 0: disables remote loopback (normal transmit and receive operation)
= 1: enables remote loopback
Analog loopback enable
= 0: disables analog loopback (normal transmit and receive operation)
= 1: enables analog loopback
Digital loopback enable
= 0: disables digital loopback (normal transmit and receive operation)
= 1: enables digital loopback
