CfCntBad_M

- Counter for Coarse Frequency Bad Event

Each time the Coarse Frequency calculates a new estimate that is bad (and then not used) this counter is in-

cremented.

CfCtrl_M

- Coarse Frequency Control

b0 :

Use_All_AMSS ‘0’=Use AMSS samples only in case of frame sync detection.

‘1’=Use AMSS samples even predidted ones.

Cf_MinKexpLow_M

- Coarse Frequency Estimation Confidence Threshold

Control of threshold value for good/bad decision of cf algorithm. This value determines the absolute minimum

of the confidence threshold value for the distinction between good and bad estimates independently of the his-

tory stored within the sliding window buffer (see register 0x072D).

Cf_DiffKexpMaxLow_M

- Coarse Frequency Estimation Confidence Threshold

Control of threshold value for good/bad decision of cf algorithm. This value is used to determine the relative min-

imum of the confidence threshold value for the distinction between good and bad estimates dependent on the

maximum frequency estimate confidence value stored in the sliding window buffer (see register 0x072D). The

relative minimum is calculated by the maximum estimate confidence value within the sliding window buffer mi-

nus the register value. The maximum value of both absolute and relative minimum values determines the lowest

confidence threshold used by the algorithm.

Cf_Delta_KexpLow_M

- Coarse Frequency Estimation Confidence Threshold

Control of threshold value for good/bad decision of cf algorithm. This value is the decrement of the threshold
