4.5.2.1
The HFINTOSC is factory calibrated but can be
adjusted in software by writing to the OSCTUNE
register (Register 4-2).
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.
