4.5.1
Using the internal oscillator as the clock source can
eliminate the need for up to two external oscillator pins,
after which it can be used for digital I/O. Two distinct
configurations are available:
• In INTIO1 mode, the OSC2 pin outputs F
• In INTIO2 mode, OSC1 functions as RA7 and
REGISTER 4-1:
DS30498C-page 36
while OSC1 functions as RA7 for digital input and
output.
OSC2 functions as RA6, both for digital input and
output.

4.5.2
The internal oscillator’s output has been calibrated at the
factory but can be adjusted in the application. This is
done by writing to the OSCTUNE register (Register 4-1).
The tuning sensitivity is constant throughout the tuning
range. The OSCTUNE register has a tuning range of
±12.5%.
When the OSCTUNE register is modified, the INTOSC
and INTRC frequencies will begin shifting to the new
8 * 32 s = 256 s); the INTOSC clock will stabilize
within 1 ms. Code execution continues during this shift.
There is no indication that the shift has occurred. Oper-
ation of features that depend on the 31.25 kHz INTRC
clock source frequency, such as the WDT, Fail-Safe
Clock Monitor and peripherals, will also be affected by
the change in frequency.
