Description
Rise/fall time control of Power Amplifier in OOK mode:
00 → 3 µs
01 →8.5 µs
10 → 15 µs
11 → 23 µs
Enables receiver low power mode by reducing LNA current
0 → Low power mode off
1 → Low power mode on (suitable for most applications)
Not used
VCO trimming:
00 → 0 mV
01 → 60 mV
10 → 120 mV
11 → 180 mV
Selection between two RF frequencies as defined by SynthRx, SynthPx, and SynthSx registers:
0 → Frequency 1
1 → Frequency 2
