value each time the algorithm lowers the confidence threshold due to bad estimates.

Cf_DeltaCntLow_M

- Coarse Frequency Estimation Confidence Threshold

Coarse Frequency Estimation Confidence Threshold Control. This value is the number of subsequent bad es-

timates for lowering the confidence threshold by a decrement of register 0x0722

Cf_MaxKexpHigh_M

- Coarse Frequency Estimation Confidence Threshold

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

of the confidence threshold value for the distinction between good and bad estimates independent of the history

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

Cf_DiffKexpMaxHigh_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

maximum 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 maximum is calculated by the maximum estimate confidence value within the sliding window buffer

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

highest confidence threshold used by the algorithm.

Cf_DeltaKexpHigh_M

- Coarse Frequency Estimation Confidence Threshold

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

value each time the algorithm enlarges the confidence threshold due to good estimates.
