Normal operation
Transmit line XL1/XL2 or XDOP/XDON are switched into high

information is frozen.
Normal operation. If a short is detected on pins XL1/2 the
transmit line monitor sets the XL1/2 outputs into a high
impedance state.
If a short is detected on XL1/2 pins automatic setting these pins
into a high impedance (by the XL-monitor) state is disabled.
