R0
R/W Deviation exponent
R0
R/W When MSK modulation is enabled:
Sets fraction of symbol period used for phase change. Refer to
the SmartRF^ Studio software [5] for correct DEVIATN setting
when using MSK.
When 2-FSK/GFSK modulation is enabled:
Deviation mantissa, interpreted as a 4-bit value with MSB implicit
1. The resulting deviation is given by:
f _dev

f _xosc
2¹⁷
 (8  DEVIATION _ M )  2^{DEVIATION _ E}
The default values give ±47.607 kHz deviation, assuming 26.0
MHz crystal frequency.
