Network Loop Code Detection Enable pin 1
Network Loop Code Detection Enable pin 0
In Hardware Mode, NLCDE[1:0] pins are used to control the Loop-Code
detection according to the following table:
When NLCDE1=”0” and NCLDE0=”1”, or NLCDE1=”1” and NLCDE0=”0”, the
chip is manually programed to monitor the receive data for the Loop-Up or
Loop-Down code respectively. When the presence of the “00001” or “001”
pattern is detected for more than 5 seconds, the NLCD pin is set to “1” and
the Host has the option to activate the loop-back function manually.
Setting the NLCDE1=”1” and NLCDE0=”1” enables the Automatic Loop-
Code detection and Remote-Loop-Back activation mode. As this mode is ini-
tiated, the state of the NLCD pin is reset to “0” and the chip is programmed to
monitor the receive data for the Loop-Up Code. If the “00001” pattern is
detected for longer than 5 seconds, the NLCD pin is set to “1”, Remote Loop-
Back is activated and the chip is automatically programed to monitor the
receive data for the Loop-Down code. The NLCD pin stays “High” 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 sec-
onds or if the Automatic Loop-Code detection mode is terminated.

I
Insert Bipolar Violation
In Hardware Mode, when this pin transitions from "0" to "1", a bipolar viola-
tion is inserted in the transmitted data stream. Bipolar violation can be
inserted either in the QRSS pattern, or input data when operating in single-
rail mode. The state of this pin is sampled on the rising edge of TCLK.
NOTE: To ensure the insertion of a bipolar violation, this pin should be reset
to a "0" prior to setting to a "1".
