PreFilter
If set to one 4 samples are combined to one data. (average)
4
RectFilter
If set to one, the ADC-values are changed to a more rectangular wave
shape
3
SyncHigh
Defines if the bit grid is fixed at maximum (1) or at minimum (0) value
of the correlation.
2
CorrInv
Defines a logical one:
0: subcarrier / no subcarrier
1
FSK
If set to 1, the demodulation scheme is set to FSK
0
BPSK
If set to 1, the modulation scheme is BPSK
