SHAPING

Shaping filter

0 (DISABLED): Filter disabled.

1 (ODDLENGTH): Filter has odd length. Filter uses coefficients 0,1,2,3,4,5,6,7,8,7,6,5,4,3,2,1,0.

2 (EVENLENGTH): Filter has even length. Filter uses coefficients 0,1,2,3,4,5,6,7,7,6,5,4,3,2,1,0.

DEMODRAWDATASEL

Demod raw data select

0 (DIS): Disabled.

1 (ENTROPY): 1-bit entropy source extracted from the RF receive chain, to be used for random number generation.

2 (ADC): 2 * 3-bit I and Q ADC data.

3 (FILTLSB): 2 * 16-bit I and Q channel filtered data downmixed to zero-IF. The receive signal chain has 19 bits dynamic range at this point, and the FILTLSB setting outputs the 16 least significant bits (with saturation).

4 (FILTMSB): 2 * 16-bit I and Q channel filtered data downmixed to zero-IF. The receive signal chain has 19 bits dynamic range at this point, and the FILTMSB setting outputs the 16 most significant bits (with truncation).

5 (FILTFULL): 2 * 19-bit I and Q channel filtered data downmixed to zero-IF. The FILTFULL option will output all 19 bits of dynamic range, sign extended to 32 bits.

6 (FREQ): 8-bit received frequency data (or logarithmic amplitude for ASK/OOK).

7 (DEMOD): 8-bit demodulated data (freq/amp/phase). When coherent detection is enabled, only the in-phase component is selected.
