Version Number of Chip
00
Equalizer Status Valid
These bits informs the user about the current state of the receive
equalization network. Only valid if LIM1.EQON is set.
00… equalizer status not valid, still adapting
01… equalizer status valid
10… equalizer status not valid
11… equalizer status valid but high noise floor
The current line attenuation status in steps of nearly 1.7 dB are
displayed in these bits. Only valid if bits EV1/0 = 01. Accuracy: +/- 2
digit, based on temperature influence and noise amplitude variations.
00000… attenuation: 0 dB

11001… max. attenuation: -34 dB
Detection:
This bit is set when the incoming signal has “no transitions” (analog
