These bits select the internal pattern and insert it into 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 (default value 00001)
Selects reference clock for transmitting internal pattern
= 0: Uses TCLK as the reference clock
= 1: Uses MCLK as the reference clock
Inverts PRBS
= 0: The PRBS data is not inverted
= 1: The PRBS data is inverted before transmission and detection
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 RDP/RDN/RCLK is disabled during LOS
= 1: AIS insertion on RDP/RDN/RCLK is enabled during LOS
Automatically Transmit All Ones (enabled only when PATT[1:0] = 00)
= 0: Disabled
= 1: Automatically Transmit All Ones pattern at TTIP/TRING during LOS
Reserved
Automatic remote loopback enable
= 0: Disables automatic remote loopback (normal transmit and receive operation)
= 1: Enables automatic remote loopback
Remote loopback enable
= 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
