All ranges selected by RSELx overlap with RSELx + 1: RSELx = 0 overlaps RSELx = 1, ... RSELx = 14 overlaps RSELx = 15.
DCO control bits DCOx have a step size as defined by parameter SDCO.
Modulation control bits MODx select how often fDCO(RSEL,DCO+1) is used within the period of 32 DCOCLK cycles. The frequency fDCO(RSEL,DCO) is used for the remaining cycles. The frequency is an average equal to:
