NLCDE1_n
Network Loop Code Detection Enable Bit 1:
This bit together with NLCDE0_n control the Loop-Code detec-
tion of each channel.
When NLCDE1 =”0” and NLCDE0 = “1” or NLCDE1 = “1” and
NLCDE0 = “0”, the chip is manually programmed to monitor
the receive data for the Loop-Up or Loop-Down code respec-
tively.When the presence of the “00001” or “001” pattern is
detected for more than 5 seconds, the status of the NLCD bit is
set to “1” and if the NLCD interrupt is enabled, an interrupt is
initiated.The Host has the option to control the Loop-Back
function manually.
Setting the NLCDE1 = “1” and NLCDE0 = “1” enables the
Automatic Loop-Code detection and Remote Loop-Back acti-
vation mode. As this mode is initiated, the state of the NLCD
interface bit is reset to “0” and the chip is programmed to mon-
itor the receive data for the Loop-Up code. If the “00001” pat-
tern is detected for longer than 5 seconds, the NLCD bit is set
“1”, Remote Loop-Back is activated and the chip is automati-
cally programmed to monitor the receive data for the Loop-
Down code. The NLCD bit stays set even after the chip stops
receiving the Loop-Up code. The Remote Loop-Back condition
is removed when the chip receives the Loop-Down code for
more than 5 seconds or if the Automatic Loop-Code detection
mode is terminated.

CODES_n
Encoding and Decoding Select:
Writing a “0” to this bits selects HDB3 or B8ZS encoding and
decoding for channel number n. Writing “1” selects an AMI
coding scheme. This bit is only active when single rail mode is
selected.
