The 12-bit parameter of the Frequency Setting Command <f11 :
f0> has the value F. The value F should be in the range of 96 and
The constants C1 and C2 are determined by
the selected band as:
3903. When F is out of range, the previous value is kept. The
synthesizer center frequency f 0 can be calculated as:
f 0 = 10 MHz * C1 * (C2 + F/4000)

The RSSI threshold depends on the LNA gain, the real RSSI threshold can be calculated:
RSSI th = RSSI setth + G LNA
Bit 0 ( en ) enables the whole receiver chain when set. Enable/disable of the wake-up timer and the low battery detector are not affected by
this setting.
Note: Clock tail is not generated when the crystal oscillator is controlled by en bit.
