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…
Length Deactivate (Down) Code
If a shorter pattern length is required, select a multiple of the required
length and repeat the pattern in LCR2.
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.
The line loopback code is transmitted unframed.
The generated PRBS is transmitted not inverted.
The PRBS is transmitted inverted.
