Reserved.
This bit selects the active edge of the TCLKn pin.
0: Falling edge. (default)
1: Rising edge.
This bit determines the active level on the TDn, TDPn and TDNn pins.
0: Active high. (default)
1: Active low.
This bit selects the line code rule for the transmit path.
0: B8ZS (in T1/J1 mode) / HDB3 (in E1 mode). (default)
1: AMI.
These bits determines the transmit system interface.
00: Transmit Single Rail NRZ Format system interface. The data is input on TDn in NRZ format and a 1.544 MHz (in T1/J1 mode)
or 2.048 MHz (in E1 mode) clock is input on TCLKn.
01: Transmit Dual Rail NRZ Format system interface. The data is input on TDPn and TDNn in NRZ format and a 1.544 MHz (in
T1/J1 mode) or 2.048 MHz (in E1 mode) clock is input on TCLKn. (default)
10: Transmit Dual Rail RZ Format system interface. The data is input on TDPn and TDNn in RZ format.
11: Reserved.
