4.4.6
The local loop-back mode, selected by LOOP.LL = 1, disconnects the receive lines
RL1 2 or ROID from the receiver. It is used in analog input applications
(LIM1.ECMIR = 0). Instead of the signals coming from the line, data provided by the
system interface is routed through the analog receiver back to the framer interface. The
bit stream is transmitted without disturbance on the transmit line. An AIS to the distant
end can be enabled by setting LIM1.XAIS without influencing the data looped back to the
system interface.
The signal codes for transmitter and receiver have to be programmed to be identical.
