The digital loop-back mode, selected by LOOP.DLB = 1, also disconnects the receive
lines RL1/2 from the receiver. It is used in digital input applications (LIM1.ECMIR = 1).
Instead of the signals coming from the line, the data provided by framer interface is
routed through the clock and data recovery circuit back to the framer interface without
touching the analog receiver part. The bit stream is transmitted on XL1/2 without
disturbance. An AIS to the distant end can be enabled by setting LIM1.XAIS without
influencing the data looped back to the framer interface.
The serial codes for transmitter and receiver have to be programmed identically.
