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 CC2510Fx and fRef = fXOSC /2 for CC2511Fx}
For CC2510Fx Min figures are given using f_XOSC = 24 MHz. Typ figures are given using f_XOSC = 26 MHz,
and Max figures are given using f_XOSC = 27 MHz. For CC2511Fx, f_XOSC = 48 MHz
