LPMOD4
I
Loop Mode 4. If driven high the loopback mode of channel 4 will be set to re-
mote loop. Otherwise theloopback mode will remain at local loop. The
actual loopback will be activated when the LOOPEN4 is asserted.

LPMOD3
I
Loop Mode 3. If driven high the loopback mode of channel 3 will be set to re-
mote loop. Otherwise the loopback mode will remain at local loop. The
actual loopback will be activated when the LOOPEN3 is asserted.
