Data Sheet
Length Activate (Up) Code
These bits defines the length of the LLB activate code which is
programmable in register LCR3.
00… length: 5 bit
01… length: 6 bit
10… length: 7 bit
11… length: 8 bit
Framed Line Loopback/Invert PRBS
Depending on bit LCR1.XPRBS this bit enables different functions:
LCR1.XPRBS=0:
0…
1…
Invert PRBS
LCR1.XPRBS=1:
0…
1…
Line Loopback Pattern
LCR1.XPRBS=0
0…
1…
LCR1.XPRBS=1 or LCR1.EPRM = 1
0…
1…
If a shorter pattern length is required, select a multiple of the required
length and repeat the pattern in LCR3.
The line loopback code is transmitted including framing bits.
LLB code overwrites the FS/DL bits.
The line loopback code is transmitted unframed. LLB code
does not overwrite the FS/DL bits.
The generated PRBS is transmitted not inverted.
The PRBS is transmitted inverted.
Fixed line loopback code according to ANSI T1. 403
(001 = loop down or 00001 = loop up).
Enable user programmable line loopback code via register
LCR2/3.
