Equalizer Status Valid
These bits informs the user about the current state of the receive
equalization network . Only vaild if LIM1.EQON is set.
00… equalizer status not vaild, still adapting
01… equalizer status vaild
10… equalizer status not vaild
11… equalizer status valid but high noise floor
Receive Equalizer Status
The current line attenuation status in steps of nearly 1.4 dB are
displayed in these bits. Only valid if bits EV1/0 = 01.
Accuracy: +/- 2 digit, based on temperature influence and noise
amplitude variations.
