The IRC is calibrated by writing to the MCGTRM register first, then using the FTRIM bit to “fine tune”
the frequency. We will refer to this total 9-bit value as the trim value, ranging from 0x000 to 0x1FF, where
the FTRIM bit is the LSB.
The trim value after reset is the factory trim value unless the device resets into any BDM mode in which
case it is 0x800. Writing a larger value will decrease the frequency and smaller values will increase the
frequency. The trim value is linear with the period, except that slight variations in wafer fab processing
produce slight non-linearities between trim value and period. These non-linearities are why an iterative
