When the low power RC oscillator is enabled,
calibration is continuously done in the background
as long as the high speed crystal oscillator is
running.

2 _{fRef = fXOSC for CC1110Fx and fRef = fXOSC /2 for CC1111Fx}
For CC1110Fx Min figures are given using f_XOSC = 26 MHz. Typ figures are given using f_XOSC = 26 MHz,
and Max figures are given using f_XOSC = 27 MHz. For CC1111Fx, f_XOSC = 48 MHz
