Idle Channel Code
If channel loop-back is enabled by programming the register
LOOP.ECLB = 1, the contents of the assigned outgoing channel on
ports XL1/XL2 or XDOP/XDON is set equal to the idle channel code
selected by this register.
Additionally, the specified pattern overwrites the contents of all
channels of the outgoing PCM frame selected by the idle channel
registers ICB(3:1). IDL7 is transmitted first.

Normal operation
Transmit line XL1/XL2 or XDOP/XDON are switched into high-
impedance state. If this bit is set the transmit line monitor status
information is frozen (default value after hardware reset).
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 pins XL1/2, the automatic setting of
these pins into a high-impedance state (by the XL-monitor) is
disabled.
