The highLowThreshold1 parameter is the logical OR of the filter high & low threshold 1 values. The bit definitions for highLowThreshold1 are as follow:

highLowThreshold1.[15:0] low threshold 1
highLowThreshold1.[31:16] high threshold 1 The upper 16 bits define the high threshold and the lower 16 bits define the low threshold. CSL_SDFM_THRESHOLD(H,L) can be used to combine the high and low thresholds.

The highLowThreshold2 parameter is the logical OR of the filter high & low threshold 2 values. The bit definitions for highLowThreshold2 are as follow:

highLowThreshold2.[15:0] low threshold 2
highLowThreshold2.[31:16] high threshold 2 The upper 16 bits define the high threshold and the lower 16 bits define the low threshold. CSL_SDFM_THRESHOLD(H,L) can be used to combine the high & low thresholds.

The zeroCrossThreshold parameter is the logical OR of the zero cross threshold enable flag and the zero-cross threshold value. The bit definitions for zeroCrossThreshold are as follows:

zeroCrossThreshold.[15] - Enable or disable zero cross threshold. Valid values are 1 or 0 to enable or disable the zero cross threshold respectively.
zeroCrossThreshold.[14:0] - Zero Cross Threshold value. The CSL_SDFM_SET_ZERO_CROSS_THRESH_VALUE(X) macro can be used as parameter zeroCrossThreshold to enable & specify the zero-cross threshold value.

Returns: None.
