CC25000x15: DEVIATN – Modem Deviation SettingBit Field Name Reset R/W Description7 Reserved R06:4 DEVIATION_E[2:0] 4 (100) R/W Deviation exponent3 Reserved R02:0 DEVIATION_M[2:0] 7 (111) R/W When MSK modulation is enabled:Sets fraction of symbol period used for phase change. Refer tothe Smart<strong>RF</strong> ® Studio software [5] for correct DEVIATN settingwhen using MSK.When 2-FSK/GFSK modulation is enabled:Deviation mantissa, interpreted as a 4-bit value with MSB implicit1. The resulting deviation is given by:fdevf=2xoscDEVIATION _ E⋅ (8 + DEVIATION _ M ) ⋅ 217The default values give ±47.607 kHz deviation, assuming 26.0MHz crystal frequency.SWRS040B Page 70 of 92
