LSB of RF carrier frequency
Frf = Fstep × Frf(23;0)
Default value: 434.000 MHz
The RF frequency is taken into account internally only when:
- entering FSRX/FSTX modes
- re-starting the receiver

Data shaping:
In FSK:
00  no shaping
01  gaussian filter BT = 1.0
10  gaussian filter BT = 0.5
11  gaussian filter BT = 0.3
In OOK:
00  no shaping
01  filtering with fcutoff = bit_rate
10  filtering with fcutoff = 2*bit_rate (for bit_rate < 125 kb/s)
11  reserved
