OOK demodulator threshold type:
00 -> fixed threshold mode
r/w 01 -> peak mode (d)
10 -> average mode
11 -> reserved
Gain on the IF chain:
00-> maximal gain (0dB) (d)
r/w 01 -> -4.5 dB
10 -> -9dB
11-> -13.5 dB
Single side frequency deviation in FSK Transmit mode:
Refer to sections 3.3.4 and 3.3.5

, 0 ≤ C ≤ 255, where C is the value in the register.
2  (C  1)*(D  1)
(d): C = “0000111” => Bit Rate = 25 kb/s NRZ
D coefficient of the bit rate

Ramp control of the rise and fall times of the Tx PA regulator output voltage in
OOK mode:
r/w
00=> 3us
01=> 8.5 us
10 => 15 us
11=> 23 us (d)
Enables the low power mode of the receiver by reducing the bias current
r/w
of the LNA.
0 -> Low power mode disabled (d)
1 -> Low power mode enabled
r/w VCO trimming: (d) 11
Selection between the two RF frequencies defined by the
r/w
SynthRi, SynthPi, and SynthSi registers:
0 -> frequency 1 for R1,P1,S1 (d)
1 -> frequency 2 for R2,P2,S2
