2.5.1.1
The HFINTOSC/MFINTOSC oscillator circuits are
factory calibrated but can be adjusted in software by
writing to the TUN<5:0> bits of the OSCTUNE register
(Register
The default value of the TUN<5:0> is ‘000000’. The
value is a 6-bit two’s complement number.
When the OSCTUNE register is modified, the
HFINTOSC/MFINTOSC frequency will begin shifting to
the new frequency. Code execution continues during this
shift. There is no indication that the shift has occurred.
The TUN<5:0> bits in OSCTUNE do not affect the
LFINTOSC frequency. Operation of features that
depend on the LFINTOSC clock source frequency, such

The PLLEN bit is active only when the HFINTOSC is the primary clock source (FOSC<2:0> = 100X) and
the selected frequency is 8 MHz or 16 MHz (IRCF<2:0> = 11x). Otherwise, the PLLEN bit is unavailable
and always reads ‘0’.

The OSCTUNE register also implements the INTSRC
and PLLEN bits, which control certain features of the
internal oscillator block.
The INTSRC bit allows users to select which internal
oscillator provides the clock source when the
31.25 kHz frequency option is selected. This is covered
in greater detail in
Selection”.
The PLLEN bit controls the operation of the frequency
multiplier, PLL, in internal oscillator modes. For more
details about the function of the PLLEN bit, see
