11.5.2 CMU_HFRCOCTRL - HFRCO Control Register

Write this register to set the frequency band in which the HFRCO is to operate. Always update all fields in this register at once by writ-
ing the value for the desired band, which has been obtained from the Device Information page entry for that band. The TUNING, FINE-
TUNING, FINETUNINGEN and CLKDIV bitfields can be used to tune a specific band (FREQRANGE) of the oscillator to a non-precon-
figured frequency. When changing this setting there will be no glitches on the HFRCO output, hence it is safe to change this setting
