principle characteristics of the DCO
D Individual devices have a minimum and maximum operation frequency. The specified parameters for
f_DCOx0 to f_DCOx7 are valid for all devices.
D The DCO control bits DCO0, DCO1 and DCO2 have a step size as defined in parameter S_DCO.
D The modulation control bits MOD0 to MOD4 select how often f_DCO+1 is used within the period of 32 DCOCLK
cycles. f_DCO is used for the remaining cycles. The frequency is an average = f_DCO × (2^MOD/32).
D All ranges selected by R_sel(n) overlap with R_sel(n+1): R_sel0 overlaps with R_sel1, ... R_sel6 overlaps with R_sel7.
