If set, BCR phase compensation will be bypassed.
If set, slicer phase compensation will be bypassed.
Dithering Type.
If low and dither enabled, we add +1/0, otherwise if high and dithering enabled,
we add ±1.
If low, the ADC Oscillation Detection mechanism is allowed to work. If set, we
disable the function.
If set, in OOK mode, the slicer threshold will be estimated by 8 bits of preamble.
By default, this bit is low and the demod estimate the threshold after 4 bits.
