3.4.1.1
OSCTUNE Register
The oscillator is factory calibrated but can be adjusted
in software by writing to the OSCTUNE register
The default value of the OSCTUNE register is ‘0’. The
value is a 5-bit two’s complement number.
When the OSCTUNE register is modified, the frequency
will begin shifting to the new frequency. Code execution
continues during this shift. There is no indication that the
shift has occurred.
