FfScale_M

- Fine Frequency Scale Factor

Factor that is multiplied with the Fine Frequency estimates to get the Frequency Control’s internally used esti-

mate. The msb bit has a weight of 0.5, i.e. a value of FF h is interpreted as a factor of 255/256. This value has

to considered together with the control constants of the Fine Frequency Control loop.

Ff_OOR_M

- Fine Frequency Out-Of-Range Counter

This counter counts up if the Fine Frequency Estimate is considered as out of range and the Fine Frequency

Control loop is reset (see register max Freq_M, addr: 0x0121/22).

EpocEn_M

- Error Phase Offset Correction Enable

If this bit is set, the EPOC algorithm inside the Post Processing is enabled

DemapCtrl_M

- Demapping Control

The Re and Im input values are cross added to get the output Re and Im values corresponding to the metric

used for the FEC. This register determines this metric generation calculations.

b7:

sign control inverts Re input value for the Re output

b6:

sign control inverts Im input value for the Re output

b5:

sign control inverts Re input value for the Im output

b4:

sign control inverts Im input value for the Im output

b3:

pass control force zero of Re input value for the Re output

b2:

pass control force zero of Im input value for the Re output

b1:

pass control force zero of Re input value for the Im output

b0:

pass control force zero of Im input value for the Im output
