RW

if '0' the PISO is of 10 bits (the whole bus) if '1' the PISO is of 8 bits 

(The LSBs) It's relevant both in normal Tx and in loopback mode. Use: '1' in PCI-E gen 

3 and CIO (if supported) '0' for all other interfaces

0h

RW

Div ration of beacon signal from ick_suslow clock '0' - Beacon freq 

will be as sus clock freq '1' - Beacon freq will be 1/4 of sus clock freq (note LFPS spec is 

10-50MHz)

RW

Used to define if we use uniq-transition-bit scaling or 

not. The purpose is to have gen dependant scaling / non-scaling When '00' - don't 

activate uniq-transition-bit When '01' - if fast-clock is not divided (gen2?) activate uniq-

transition-bit otherwise (gen1?) don't. When '10' - if fast-clock is not divided or divided 

by 2 (gen2?) activate uniq-transition-bit otherwise (gen1?) don't. (will probably be 

down-scaling amount of slices) When '11' - activate uniq-transition-bit

27:26

3h

RW

Used to define if we use scaling of the compansation 

values or not. The purpose is to have gen dependant scaling / non-scaling When '00' - 

don't used scaled comp When '01' - if fast-clock is not divided (gen2?) don't scale-comp 

otherwise (gen1?) use scaled-comp When '10' - if fast-clock is not divided or divided by 

2 (gen2?) don't scale-comp otherwise (gen1?) use scaled-comp (will probably be down-

scaling amount of slices) When '11' - if fast-clock is not divided (gen2?) use scaled-

comp otherwise (gen1?) don't use scaled-comp (will probably be up-scaling amount of 

slices)

RW

Used to select scaling of -3.5dB deemphasis either 

ow2tapgen1deemph3p5[7:0] or ow2tapgen2deemph3p5[7:0] When '0' - if fast-clock is 

not divided use gen2 otherwise use gen1 When '1' - if fast-clock is not divided or 

divided by 2 use gen2 otherwise use gen1

0h

RW

when margin='001', this bit with dataratefit are used to 

select between margin000 (for gen2) and margin101 (for gen1) when '0' - if fast-clock 

is not divided use margin000 (gen2) otherwise use margin101 (gen1) when '1' - if fast-

clock is not divided or divided by 2 use margin000 (gen2) otherwise use margin101 

(gen1)

RW

factor (X/128) of slices to use in main-R1 for full swing level. Used 

for ~1V p2p to be used in Gen1 mode (Gen1/Gen2 depends on dataratefit and 

downscaleamp register)
