2.6.2
The internal oscillator block is calibrated at the factory
to produce an INTOSC output frequency of approxi-
mately
Table 26-8.)
The INTOSC frequency can be adjusted using the
TUN5:TUN1
OSCTUNE<5:1>. OSCTUNE<0> has no effect, but is
readable and writable, enabling changes of the
INTOSC frequency using two increment or decrement
instructions.
The internal oscillator’s output can be adjusted in the
user’s application. This is done by writing to the
OSCTUNE
sensitivity is constant throughout the tuning range.

When the OSCTUNE register is modified, the INTOSC
and INTRC frequencies begin shifting to the new fre-
quency. The INTOSC and INTRC clocks will stabilize at
the new frequency within 100 μs. Code execution
continues during this shift.
There is no indication when the shift occurs. Operation
of features that depend on the INTRC clock source
frequency also will be affected by the change in
frequency. This includes the WDT, Fail-Safe Clock
Monitor and peripherals.
