6.4.1.5. Peak Deviation 1
The peak deviation for FSK transmissions is determined by the peak deviation 1 register and the peak deviation 0 register. This value
is also used inside the DFT FSK detector. Calculation of the value for the peak deviation is straightforward:
The result of this equation, converted to Hex, is entered into the peak deviation registers.
