Automatic Clock-Switching
If TCLK is missing, the transmit clock can optionally be switched to
the SYNC clock automatically.
0 =
1 =
To verify transmit data, the receive line supervision circuitry can be
switched to the transmit path. If selected, data input on pins XDIP/
XDIN is checked for BiPolar Violations (BPV), EXzessive Zeros (EXZ)
and Loss Of Signal (LOS).

Note: Transmit data performance monitoring is not possible in
Transmit Line Biasing
The analog circuit of the transmit line driver can be switched into a
power saving mode. This slightly reduces the output slopes on
XL1/2.

Transmit Line Monitor Enable
The transmit line monitor circuit can be switched off to reduce power
consumption.
