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.
