PIC16F87/88
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:
DS30487C-page 38
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 fre-
quency. The INTRC clock will reach the new frequency
within 8 clock cycles (approximately 8 * 32 s = 256 s);
the INTOSC clock will stabilize within 1 ms. Code execu-
tion continues during this shift. There is no indication that
the shift has occurred. Operation 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.
