TUNING
Writing this field adjusts the LFRCO frequency (the higher value, the higher frequency). This field is updated with the production
calibrated value during reset, and the reset value might therefore vary between devices.
Reserved
BAND
Write this field to set the frequency band in which the AUXHFRCO is to operate. When changing this setting there will be no glitches
on the HFRCO output, hence it is safe to change this setting even while the system is using the AUXHFRCO. To ensure an accurate
frequency, the AUXTUNING value should also be written when changing the frequency band. The calibrated tuning value for the
different bands can be read from the Device Information page. Flash erase and write use this clock. If it is changed to another value
than the default, MSC_TIMEBASE must also be configured to ensure correct flash erase and write operation.
TUNING
This value has been set during calibration and should not be changed.
