    OSCTUNE Register
    The HFINTOSC is factory calibrated but can be
    adjusted in software by writing to the OSCTUNE
    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
    HFINTOSC frequency will begin shifting to the new
    frequency. Code execution continues during this shift.
    There is no indication that the shift has occurred.
    OSCTUNE does not affect the LFINTOSC frequency.
    Operation of features that depend on the LFINTOSC
    clock source frequency, such as the Power-up Timer
    (PWRT), Watchdog Timer (WDT), Fail-Safe Clock
    Monitor (FSCM) and peripherals, are not affected by the
    change in frequency.
