Network Loop Code Detection Enable [1:0]:
These bits are used to control the Loop-Code detection on the
receive path, according to the table below. This part must be in Sin-
gle Rail mode to detect..
Loop-Up Code Detection Enable:
The XRT86VL30 is configured to monitor the receive data for the
Loop-Up code Pattern (i.e. a string of four ‘0’s followed by one ‘1’
pattern). When the presence of the “00001” pattern is detected for
more than 5 seconds, the status of the NLCD bit (bit 3 of register
0x0F05) is set to “1” and if the NLCD interrupt is enabled (bit 3 of
register 0x0F04), an interrupt will be generated.
Loop-Down Code Detection Enable:
The XRT86VL30 is configured to monitor the receive data for the
Loop-Down code Pattern (i.e. a string of two ‘0’s followed by one ‘1’
pattern). When the presence of the “001” pattern is detected for
more than 5 seconds, the status of the NLCD bit (bit 3 of register
0x0F05) is set to “1” and if the NLCD interrupt is enabled (bit 3 of
register 0x0F04), an interrupt will be generated.
Automatic Loop-Up Code Detection and Remote Loop Back
Activation Enable:
When this mode is enabled, the state of the NLCD bit (bit 3 of regis-
ter 0x0F05) is reset to “0” and the XRT86VL30 is configured to mon-
itor the receive data for the Loop-Up code. If the “00001” pattern is
detected for longer than 5 seconds, then the NLCD bit (bit 3 of regis-
ter 0x0F05) is set “1”, and Remote Loop-Back is activated. Once the
remote loop-back is activated, the XRT86VL30 is automatically pro-
grammed 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 only when the
XRT86VL30 receives the Loop-Down code for more than 5 seconds
or if the Automatic Loop-Code detection mode is terminated.
