ADCDIV: ADC Sampling Rate Division Factor.
The ADC sampling rate factor must be calculated together with
Note that for better performance, the highest possible ADC sampling rate
should be set.
RSSI Detector Start-up Delay
Min: 00h: 0 bit delay (Start with first bit after FSYNC)
Max: FFh: 255 bits delay
ASKSCA: CIC-filter Input Scaling Factor
000b: default
ASKDEL: CIC-filter cmb Section delay Factor
110b: default
For better performance from reduced duty and data rate errors set 111b.
